--- version: alpha name: notion.so description: "Light product system built on #ffffff with #455dd3 as the primary CTA accent. Type anchored in NotionInter at 54px / weight 700. Extracted automatically from https://notion.so/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)." narrative: | notion.so is built on a pure-white canvas (rgb(255, 255, 255)). The system uses rgb(69, 93, 211) as the accent for primary actions and brand signals. Crisp CTAs (4px radius) reinforce a precise, technical aesthetic alongside NotionInter as the primary typeface. NotionInter is paired with Inter for secondary roles. A layered elevation system (6 distinct shadows) building a clear front-to-back hierarchy. Motion is a first-class concern — 39 keyframe animations plus transition-driven interactions. colors: background: "#ffffff" surface-1: "#f6f5f4" surface-2: "#fcf8f5" ink-subtle: "#615d59" primary: "#455dd3" on-primary: "#ffffff" primary-hover: "#f2f9ff" hairline: "rgba(255, 255, 255, 0)" primary-focus: "#0075de" semantic-error: "#f64932" semantic-success: "#14832b" semantic-warning: "#ff6d00" typography: display-xl: fontFamily: "NotionInter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 64px fontWeight: 700 lineHeight: 1 letterSpacing: -2.125px display-md: fontFamily: "NotionInter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 14px fontWeight: 400 lineHeight: 1.43 letterSpacing: 0 body: fontFamily: "NotionInter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 12px fontWeight: 500 lineHeight: 1.33 letterSpacing: 0.125px body-sm: fontFamily: "NotionInter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 12px fontWeight: 500 lineHeight: 1.33 letterSpacing: 0.125px caption: fontFamily: "NotionInter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 22px fontWeight: 700 lineHeight: 1.27 letterSpacing: -0.25px button: fontFamily: "NotionInter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 500 lineHeight: 1.5 letterSpacing: 0 rounded: none: 0px xs: 4px sm: 8px md: 12px lg: 16px xl: 9999px spacing: xxs: 2px xs: 12px sm: 16px md: 20px lg: 26px xl: 32px xxl: 64px components: button-ghost: backgroundColor: "{colors.hairline}" textColor: "{colors.surface-1}" typography: "{typography.button}" rounded: "{rounded.xs}" padding: 5px 10px button-primary-brand: backgroundColor: "{colors.primary}" textColor: "{colors.on-primary}" typography: "{typography.button}" rounded: "{rounded.sm}" padding: 4px 14px button-primary-brand-2: backgroundColor: "{colors.primary}" textColor: "{colors.on-primary}" typography: "{typography.button}" rounded: "{rounded.sm}" padding: 6px 15px input-text-input: backgroundColor: "{colors.hairline}" textColor: "#000000" typography: "{typography.button}" rounded: "{rounded.xs}" padding: 7px 10px 7px 30px navigation-main-nav: backgroundColor: "{colors.hairline}" typography: "{typography.button}" rounded: "{rounded.none}" padding: 80px 0px 0px testimonial-quote-card: backgroundColor: "{colors.surface-1}" textColor: "#000000" typography: "{typography.button}" rounded: "{rounded.md}" padding: 24px tab-ghost-tab: backgroundColor: "{colors.hairline}" textColor: "#000000" typography: "{typography.button}" rounded: "{rounded.sm}" padding: 12px 16px extracted_at: "2026-06-11T05:01:50.585Z" completeness: 91 scoreVersion: "v2" --- # Design System — notion.so > Extracted automatically by Prism from https://notion.so > Date: 2026-06-11 > Viewport: Desktop 1440x900 + Mobile 390x844 > Values are extracted, not hand-written: rendered styles via getComputedStyle() + colors declared in CSS custom properties (token-only values are marked `(token)` and may not be painted). ## 0.

Skip §11–12 unless extending. ## 1. Visual Theme & Atmosphere notion.so uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight. Typography is anchored in **NotionInter**, deployed with OpenType features enabled globally (`"lnum", "locl" 0`). These aren't decorative — they're load-bearing: without them, the typeface reverts to its generic state and the design loses its specific texture. The weight scale rejects the standard 100/200/.../900 ladder in favor of custom values (max **700** in this system) — a deliberate signal that this design system is precisely tuned, not assembled from defaults. Negative letter-spacing at display sizes (-2.125px at 64px) compresses headlines into engineered blocks, dense and precise. Body text reads in Translucent Black (95%) (`rgba(0, 0, 0, 0.95)`) (contrast ratio 21.0:1, well above WCAG AA). **Royal Blue** (`#455dd3`) is the single high-saturation color in the system — it earns its presence only on interactive elements, making CTAs and links the unmistakable focal points against the otherwise neutral palette. Elevation is built from multi-layer shadow stacks (6 distinct) — each combines several blurred layers at varying offsets to build a clear front-to-back hierarchy. Border radius varies from pill-shaped (fully rounded) to moderately rounded elements, creating visual rhythm. Motion design uses smooth easing curves for polished state transitions. **Key Characteristics:** - Background: Banner (`#ffffff`) - Primary typeface: NotionInter - Accent: Royal Blue (`#455dd3`) - Display: 64px weight 700, letter-spacing -2.125px - Shadow system: 6 distinct elevation levels - Custom fonts loaded: NotionInter, Lyon Text, iA Writer Mono, Permanent Marker ## 2.

Typography Rules ### Font Families - **Primary**: `NotionInter` - **Secondary**: `Noto Sans Arabic` - **Font 3**: `Noto Sans Hebrew` - **Font 4**: `Lyon Text` - **Font 5**: `iA Writer Mono` ### Custom Fonts Loaded - **NotionInter** weight 400 (normal) - **NotionInter** weight 500 (normal) - **NotionInter** weight 600 (normal) - **NotionInter** weight 700 (normal) - **Noto Sans Arabic** weight 100 900 (normal) - **Noto Sans Hebrew** weight 100 900 (normal) - **Lyon Text** weight 400 (normal) - **Lyon Text** weight 600 (normal) - **iA Writer Mono** weight 400 (normal) - **iA Writer Mono** weight 600 (normal) - **Permanent Marker** weight 400 (normal) ### Typography Hierarchy | Role | Font | Size | Weight | Line Height | Letter Spacing | Notes | |------|------|------|--------|-------------|----------------|-------| | Display Hero | NotionInter | 64px | 700 | 1 | -2.125px | Main headline (h1) | | Caption / Badge | NotionInter | 22px | 700 | 1.27 | -0.25px | small text (22px) | | Card Title | NotionInter | 16px | 400 | 1.5 | normal | Card headings | | Button Large | NotionInter | 16px | 500 | 1.5 | normal | Button label (16px) | | Sub-heading | NotionInter | 14px | 400 | 1.43 | normal | Third-level heading (h3) | | Caption / Badge | NotionInter | 14px | 500 | 1.43 | normal | small text (14px) | | Link Small | NotionInter | 12px | 500 | 1.33 | 0.125px | Link (12px) — Decoration: none | ### Font Weight Scale CSS custom properties define 8 explicit weight steps: - `--font-weight-regular`: `400` — Regular - `--font-weight-variable-regular`: `420` — Regular (custom, ~400) - `--font-weight-medium`: `500` — Medium - `--font-weight-variable-medium`: `520` — Medium (custom, ~500) - `--font-weight-semibold`: `600` — SemiBold - `--font-weight-variable-semibold`: `620` — SemiBold (custom, ~600) - `--font-weight-variable-bold`: `680` — Bold (custom, ~700) - `--font-weight-bold`: `700` — Bold ### Full Font Size Scale Sizes detected in the design (descending): `64px`, `54px`, `48px`, `40px`, `32px`, `26px`, `24px`, `22px`, `20px`, `16px`, `14px`, `12px` > 7 size(s) detected outside the sampled hierarchy (54px, 48px, 40px, 32px, 26px, 24px, 20px). These appear on elements not in the sampled set — likely additional display sizes, marketing-section overrides, or third-party-widget styles. ### OpenType & Variable Font Features The typography uses these OpenType features intentionally — this is a sophisticated type system, not a default fallback: - **lining figures** (`lnum`) — full-height numbers, more authoritative than old-style - **case-sensitive forms** (`case`) — punctuation height adjusted for uppercase contexts - **capital spacing** (`cpsp`) — added tracking on uppercase for breathing room - **localized forms** (`locl`) — glyphs swapped based on script/locale **Clone instruction:** Enable these in your CSS: ```css body { font-feature-settings: "lnum", "locl", "case", "cpsp"; } ``` ## 4.

Layout Principles ### Layout Type **top-nav + content** ### Grid Single column, centered content ### Max Width 78.25rem ### Spacing System Compact spacing — information density prioritized | Token | Value | |-------|-------| | xxs | 2px | | xs | 12px | | sm | 16px | | md | 20px | | base | 24px | | lg | 26px | | xl | 32px | | 2xl | 48px | | 3xl | 64px | ### Border Radius Scale | Name | Value | Use | |------|-------|-----| | None | 0px | No rounding | | Xs | 4px | Tiny corners (badges, micro elements) | | Sm | 8px | Buttons, inputs, small elements | | Md | 12px | Cards, containers | | Lg | 16px | Large rounded elements, pill segments | | Xl | 9999px | Category strips, featured containers | | Full | 9999px | Pills, avatars, circular elements | ### Shape Language | Component | Border Radius | |-----------|---------------| | Buttons | `4px` | | Inputs & Forms | `5px` | | Navigation | `none` | | Testimonials | `12px` | | Tabs | `8px` | | Page Body | `0px` | | Primary Input | `5px` | **Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill. **Full Radius Spectrum**: 0px, 4px, 5px, 8px, 12px, 16px, full/pill (from `allBorderRadii` scan) ## 5b. Spacing Rhythm Names **Measured section padding**: bands use ~29px internal vertical padding (up to 80px) — **compact**. (Distinct from the gap *between* sections above.) Reproduce this generous vertical breathing room; cramped spacing is the #1 tell of a cheap clone. *Named spacing tokens with explicit use cases. Use these names in YOUR code instead of raw pixels for consistency.* | Name | Value | Use case | |------|-------|----------| | **hero** | `64px` | Top/bottom of full-bleed hero sections | | **section** | `32px` | Between major bands (color change, content shift) | | **subsection** | `26px` | Within a section, between content groups | | **card** | `20px` | Card padding, list-item spacing | | **compact** | `16px` | Form fields, tight clusters, badge padding | | **micro** | `12px` | Icon-text gap, tag inner padding | **Agent rule**: NEVER hardcode raw pixel values for spacing in generated UI. Always reference these named tokens (`spacing-rhythm.section`, etc.). ## 5c. Widget & Structure Library Structural patterns extracted from the page DOM — these are the **blueprints** an agent should follow to reproduce the page architecture (not just CSS values). **6/8 structural patterns detected.** ### Hero Pattern - **Composition:** centered — Centered composition — heading + subheading + CTAs stacked vertically, content centered horizontally. Common for SaaS marketing pages. - **Viewport coverage:** 256px tall (not full-viewport) - **Heading:** "Meet the night shift." — 64px center-aligned - **Subheading:** "Notion agents keep work moving 24/7. They capture knowledge, answer questions, and push projects forward—all while you sleep." - **CTAs:** 2 (primary: "Get Notion free") - **Clone instruction:** Reproduce the **centered** layout.

Do's and Don'ts ### Do - Use NotionInter as the primary typeface — it defines the brand personality - Use negative letter-spacing (-2.125px) at display sizes for compressed, editorial headlines - Use the extracted shadow patterns for elevation — they are tuned to match the brand palette - Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles) - Use Royal Blue (`#455dd3`) as the primary accent — it's the brand's signature interactive color - Use 8px border-radius on buttons — the standard corner rounding for interactive elements - Style form inputs with a `1px solid rgba(0, 0, 0, 0.08)` border — use border-based inputs, not floating labels or underline-only - Maintain nav height at 64px — consistent vertical space for the navigation bar - Include exactly 2 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose - Include a theme toggle in the nav — dark mode is a first-class feature - Each card includes a top image — imagery is part of the card identity, not optional - Show company logos with testimonials — social proof relies on brand recognition, not avatars - Lay out testimonials in a grid (12+ items) — quantity signals scale and trust ### Don't - Don't substitute with generic sans-serif or serif — the custom font carries the brand - Don't increase letter-spacing on headings — the type is designed to run tight at scale - Don't invent new shadow values — use only the extracted shadow levels - Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements - Don't introduce additional saturated accent colors — the palette is intentionally controlled - Don't remove the input border — the border is the primary affordance indicator for form fields - Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence - Don't make the nav sticky — this design lets it scroll away to maximize content focus ## 7b. Enforceable Brand Rules *Structured Do/Don't with reasoning and validation tests. Agents can programmatically verify generated UI.* ```yaml rules: - id: brand-canvas-001 type: do rule: "Always use the page background `rgb(255, 255, 255)` as the base canvas" why: "Every component is designed to composit against this exact tone" test: "document.body.style.backgroundColor === 'rgb(255, 255, 255)'" - id: brand-accent-001 type: do rule: "Reserve `rgb(69, 93, 211)` for primary CTAs and brand-mark signals only" why: "Single chromatic assertion device — overuse dilutes meaning" test: "querySelectorAll('[style*=\"rgb(69, 93, 211)\"]').length <= 3 per fold" ``` ## 9. Responsive Behavior ### Breakpoints | Name | Width | Key Changes | |------|-------|-------------| | Mobile | 375px | Single column, compact spacing | | Mobile Large | 640px | Expanded mobile layout | | Tablet | 768px | Multi-column grids begin | | Desktop | 1032px | Full feature layout | | Desktop | 1120px | Full feature layout | | Desktop | 1280px | Full feature layout | | Large Desktop | 1440px | Maximum content width | ### Token Diff — Desktop vs Mobile | Element | Property | Desktop | Mobile | |---------|----------|---------|--------| | heading | font-size | `64px` | `54px` | | heading | line-height | `64px` | `56px` | | heading | letter-spacing | `-2.125px` | `-1.875px` | | button | width | `90.3906px` | `auto` | | card | width | `436.062px` | `310px` | ### Collapsing Strategy - Headlines: 64px → 54px on mobile - Navigation: horizontal links → hamburger menu on mobile - Cards: multi-column → stacked vertical on mobile - Footer: multi-column → stacked single column on mobile ### Touch Targets - Buttons: 5px 10px padding - Navigation: adequate spacing between items - Interactive elements: minimum 44px touch target recommended ### Collapsing Narrative How the structural patterns adapt from desktop to mobile (extracted from both viewport extractions): - **Navigation collapses to hamburger** — 5 links visible on desktop, 0 on mobile (the rest hide behind a menu toggle). ## 7c. Visual Effects & Dynamic Behavior *The live/dynamic layer beyond static CSS — reproduce these, not flat substitutes. This is often what separates a faithful clone from a wireframe.* - **Glassmorphism** — 1 frosted/blur layer(s) (e.g. `blur(12px)`). - **Clip-path shapes** — 4 non-rectangular cut(s). - **Blend modes** — 2 mix-blend layer(s). - **Scroll-driven reveals** — content animates in on scroll (CSS scroll-timeline). Build fade/translate reveal-on-scroll for below-fold bands. - **CSS-variable animations** (5) — animated custom properties. > **Motion fingerprint**: glassmorphism (1 layers), non-rectangular shapes (4), blend modes, CSS scroll-driven animations ## 9b. Visual Tone & Photography **Tone:** Mixed photography + illustration A balanced mix of photographic content and vector graphics. Photos likely carry product/lifestyle context while SVG handles icons, logos, and decorative accents. **Canonical Brand Image (OG):** - https://www.notion.com/front-static/meta/custom-agents-og.png *This is the image shown when the site is shared on social media — represents the brand visual essence.* **Hero Image (above-fold dominant visual):** - Aspect: 1.19:1 (landscape) - Rendered size: 192×161px - *Use this aspect ratio + composition for your clone's hero — mimicking the proportion preserves the visual hierarchy.* **Aspect Ratio Distribution:** - Landscape (1.15–2.3): 6 (30%) - Portrait (<0.87): 3 (15%) - Square (0.87–1.15): 9 (45%) - Ultra-wide (>2.3): 2 (10%) **Media Format Mix:** - SVG: 3 (icons, illustrations, decorative geometry) **Average rendered image size:** 286×243px **Above-fold image count:** 6 / 20 **Decorative Patterns Detected:** - 1 multi-stop linear gradient (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth - 2 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents - **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic **Clone instruction for decorative work:** Glassmorphism is a brand signature — use `backdrop-filter: blur(20px)` on overlapping surfaces. **Imagery Guidance for clones:** - Mix photography and illustration intentionally: photos for product/context, vectors for icons + decorative accents. - Respect the format split — replacing JPGs with illustrations (or vice versa) will shift the brand tone. ## 10. Agent Prompt Guide ### Quick Reference - Background: Banner (`#ffffff`) - Primary text: Translucent Black (95%) (`rgba(0, 0, 0, 0.95)`) - Accent: Royal Blue (`#455dd3`) - Border: Transparent (`transparent`) - Font: NotionInter - Body: 16px weight 400 ### Example Component Prompts - "Create a hero section on Banner background (#ffffff). Headline at 64px NotionInter weight 700, line-height 1, letter-spacing -2.125px, color rgba(0, 0, 0, 0.95)." - "Create the primary CTA button: `#455dd3` background, `#ffffff` text, 8px border-radius, 4px 14px padding, 500 weight, NotionInter font." - "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px." - "Build navigation: relative on `#ffffff`. NotionInter 16px weight 400 for links." ### Iteration Guide 1. **Canvas**: Set the light canvas to Banner (`#ffffff`) — every component is composited against this exact base. 2. **Typography**: All type in NotionInter, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint. 3. **Accent**: Royal Blue (`#455dd3`) — one accent, applied consistently to CTAs, active states, and links. Never introduce a second saturated color. 4. **Motion**: All transitions use `cubic-bezier(0.45,0,0.55,1)`. Timing: 100ms for micro-interactions, 200ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality. 5. **Shape**: CTAs at `4px`, cards at `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values. 6. **Spacing**: Use the `--ca-space-*` token scale (12px–32px). All padding, margin, and gap values are multiples from this scale — no magic numbers. 7. **Tokens**: Import from §11 CSS Export (`--ca-*` vars). Never hardcode hex values — always reference a token so theming remains consistent. ## 11. CSS Design Tokens Raw Export *Copy-paste ready `:root {}` block — all values extracted directly from the live site.* ```css /* Colors */ :root { --ca-on-primary: #ffffff; --ca-surface-1: #f6f5f4; --ca-surface-2: #fcf8f5; --ca-ink-subtle: #615d59; --ca-primary: #455dd3; --ca-primary-hover: #f2f9ff; --ca-hairline: transparent; --ca-primary-focus: #0075de; --ca-semantic-error: #f64932; --ca-semantic-success: #14832b; --ca-semantic-warning: #ff6d00; } /* Typography */ :root { --ca-font-primary: "NotionInter", system-ui, sans-serif; --ca-text-display: 64px; --ca-text-body: 12px; --ca-text-small: 12px; --ca-text-caption: 22px; --ca-text-button: 16px; } /* Spacing & Radius */ :root { --ca-space-xxs: 2px; --ca-space-xs: 12px; --ca-space-sm: 16px; --ca-space-md: 20px; --ca-space-base: 24px; --ca-space-lg: 26px; --ca-space-xl: 32px; --ca-space-2xl: 48px; --ca-space-3xl: 64px; --ca-radius-none: 0px; --ca-radius-xs: 4px; --ca-radius-sm: 8px; --ca-radius-md: 12px; --ca-radius-lg: 16px; --ca-radius-xl: 9999px; --ca-radius-full: 9999px; } ``` ## 13. Page Structure Skeleton *The actual layout the source site uses. Reproduce these sections in order to match the site structure.* ```yaml page-skeleton: - section: hero tag: div height: 6812px width: full-bleed layout: block children: 1 - section: feature-section tag: main height: 6394px width: full-bleed layout: block children: 4 vertical-padding: ~64px (generous) - section: feature-section tag: div height: 1117px width: full-bleed layout: flex-column justify=normal children: 3 vertical-padding: ~28px - section: feature-section tag: div classes: ["isCampaignAgentsHomepageHero"] height: 1149px width: full-bleed layout: block children: 1 bg: "rgb(2, 9, 58)" tone: dark padding: "0px 0px 32px" - section: gallery-grid tag: div height: 953px width: full-bleed layout: grid: 3-col gap=40px normal children: 5 vertical-padding: ~28px padding: "56px 105.6px 0px" - section: header tag: header classes: ["flex", "flex-col", "items-stretch", "justify-start"] height: 256px width: 960px layout: flex-column justify=start children: 3 vertical-padding: ~40px padding: "80px 0px 0px" - section: unknown tag: div height: 601px width: 960px layout: block children: 2 - section: feature-section tag: section height: 647px width: 1229px layout: flex-column justify=normal children: 2 - section: feature-section tag: div height: 3235px width: 1229px layout: flex-column justify=normal children: 2 - section: content-section tag: section height: 559px width: 1229px layout: block children: 1 bg: "rgb(255, 255, 255)" - section: header tag: header height: 96px width: 436px layout: flex-column justify=normal children: 2 bg: "rgb(255, 255, 255)" - section: logo-strip tag: section height: 182px width: 1229px layout: block children: 1 - section: feature-section tag: section height: 1037px width: 1229px layout: flex-column justify=normal children: 2 - section: header tag: header height: 366px width: 498px layout: flex-column justify=normal children: 2 bg: "rgb(255, 255, 255)" vertical-padding: ~24px padding: "24px" - section: header tag: header height: 108px width: 602px layout: flex-column justify=normal children: 2 bg: "rgb(255, 255, 255)" vertical-padding: ~24px padding: "24px" - section: header tag: header height: 108px width: 602px layout: flex-column justify=normal children: 2 bg: "rgb(255, 255, 255)" vertical-padding: ~24px padding: "24px" - section: feature-section tag: section height: 1037px width: 1229px layout: flex-column justify=normal children: 2 - section: header tag: header height: 108px width: 602px layout: flex-column justify=normal children: 2 bg: "rgb(255, 255, 255)" vertical-padding: ~24px padding: "24px" - section: header tag: header height: 108px width: 602px layout: flex-column justify=normal children: 2 bg: "rgb(255, 255, 255)" vertical-padding: ~24px padding: "24px" - section: header tag: header height: 366px width: 498px layout: flex-column justify=normal children: 2 bg: "rgb(255, 255, 255)" vertical-padding: ~24px padding: "24px" - section: feature-section tag: section height: 787px width: 1229px layout: block children: 3 - section: feature-section tag: div height: 787px width: 1229px layout: flex-column justify=normal children: 1 - section: card-grid tag: div height: 659px width: 1229px layout: grid: 3-col gap=24px children: 3 vertical-padding: ~29px - section: feature-section tag: section height: 839px width: 1229px layout: block children: 3 - section: feature-section tag: div height: 839px width: 1229px layout: flex-column justify=normal children: 1 ``` **Agent rule**: rebuild sections in this order (sorted by vertical position). Match the layout primitive (grid N-col / flex direction / block). ## 14. Copy Library (Real Content from Source) *Actual text content extracted from the live page. Use these strings verbatim when reproducing the site — they carry the brand voice.* ```yaml copy: section-headings: - "Keep work moving 24/7." - "Automate repetitive work for your team." - "You assign the tasks. Notion Agent does the work." - "One search for everything." sub-headings: - "See what Custom Agents can do" - "Triage product feedback→" - "Create your own Custom Agent→" - "Get started on Notion" ctas: - "Product" - "Get Notion free" - "Request a demo" - "Pause" navigation: - "Developers" - "Enterprise" - "Pricing" - "Request a demo" - "Get Notion free" - "Log in" - "About us" - "Careers" - "Security" - "Status" footer-links: - "About us" ``` **Agent rule**: reuse these exact strings when generating UI. Do NOT translate or rephrase — brand voice is preserved through the original wording. ## 15. Asset Inventory (Image Roles & Ratios) *Image inventory classified by role and aspect ratio. When reproducing the site, allocate this number of assets per role.* ```yaml assets: logo: count: 16 avg-ratio: 3.43 common-aspect: "~16:6 banner" sample-alts: - "OpenAI" - "Figma" - "Ramp" product: count: 3 avg-ratio: 1.12 common-aspect: "~1:1 square" sample-alts: - "Search results showing information from Slack, Google Drive," thumbnail: count: 23 avg-ratio: 1.00 common-aspect: "~1:1 square" ``` **Agent rule**: when generating placeholder images, match these counts and aspect ratios. Use neutral placeholder backgrounds for `product` (e.g. `#f5f5f5`), full-color photography hints for `hero` and `editorial`. ## 16. Component HTML Templates *Suggested HTML markup for reproducing the key components — based on what was detected in the source DOM.* ### Button (primary action) ```html ``` _Source pattern detected: padding `5px 10px` · radius `4px` · weight `400`_ ### Generic Card ```html
``` _Source pattern detected: padding `24px` · radius `12px` · shadow `none`_ **Agent rule**: use these markup skeletons as the structural baseline. Apply tokens from §2-3 for visual styling. ## 17. Content Architecture & Resources (Links by Purpose) *The page's links classified by purpose — the information architecture to reproduce. Categories, featured images, devices and projects are extracted from the rendered DOM, not guessed.* **By purpose:** **nav** 3 · **cta** 2 · **auth** 1 · **product** 16 · **pricing** 1 · **docs** 1 · **blog** 1 · **project** 17 · **social** 5 · **footer** 11 · **other** 2 **Primary actions (conversion path):** - Primary call-to-action — "Get Notion free" (the conversion path) → `https://www.notion.com/signup?from=marketing&pathname=%2F&tid=w_e96d797b273b46e48863c7a7c66a3bfb` - Account access — "Log in" (login/signup) → `https://www.notion.com/login?from=marketing&pathname=%2F&tid=w_e96d797b273b46e48863c7a7c66a3bfb` - Primary call-to-action — "in your browser" (the conversion path) → `https://www.notion.com/signup` **Projects / case studies detected** (clustered by URL + featured image): *Customers* — high confidence, 10 items: | Title | Featured image | Link | |---|---|---| | OpenAI | `Company_openai__Colorway_White.svg` (ar 2.75) | https://www.notion.com/customers/openai | | Figma | `figma-white.svg` (ar 1.96) | https://www.notion.com/customers/figma | | Ramp | `Company_Ramp__Colorway_White.svg` (ar 3.13) | https://www.notion.com/customers/ramp | | Cursor | `Company_Cursor__Colorway_White.svg` (ar 3.42) | https://www.notion.com/customers/cursor | | Vercel | `Company_Vercel__Colorway_White.svg` (ar 3.29) | https://www.notion.com/customers/vercel | | Clay | `clay-mono.svg` (ar 2.83) | https://www.notion.com/customers/clay | | Remote | `Company_Remote__Colorway_White.svg` (ar 3.24) | https://www.notion.com/customers/remote | | Faire | `Company_faire__Colorway_White.svg` (ar 3.71) | https://www.notion.com/customers/faire | **Signals:** 28/60 links carry a featured image · dominant link roles: content-card (31), footer-link (23), navigation (3). --- ## Extraction Completeness: 91/100 (A) | Category | Score | Max | Detail | |----------|-------|-----|--------| | Colors & Palette | 24 | 25 | 17 named colors | | Typography | 18 | 20 | 7 roles defined | | Components | 20 | 20 | 5 specs extracted | | Motion & Interaction | 15 | 15 | Keyframes, easing vars | | CSS Custom Properties | 10 | 10 | 810 vars | | Responsive Breakpoints | 5 | 5 | 7 breakpoints | | Variable Fonts | 0 | 5 | None detected | ## 12.
