real render · source of truth

biomejs.dev is built on a pure-white canvas (rgb(255, 255, 255)). The system uses rgb(0, 101, 218) as the high-saturation accent for primary actions. Moderately rounded CTAs (8px) — modern SaaS standard, neither sharp nor pill alongside -apple-system as the primary typeface. A restrained elevation system (2 distinct shadows) — shadows reserved for the few elements that must lift off the page. Motion is minimal — a few targeted transitions, no decorative animation.

Do's & Don'ts

21 enforceable rules pulled verbatim from the spec

Use Helvetica Neue as the primary typeface — it defines the brand personality

Keep font weights between 400-600 — the system uses a narrow weight range for subtle hierarchy

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 M Tricolor Blue (`#0065da`) as the primary accent — it's the brand's signature interactive color

Use small 4.8px radius for buttons — this design system uses subtle rounding, not pill shapes

Style form inputs with a `1px solid rgb(192, 194, 199)` border — use border-based inputs, not floating labels or underline-only

Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room

Build the hero as a split layout with media on the left — text and visual share equal weight

Include exactly 2 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose

Make the navigation fixed — it stays visible during scroll, signaling content depth

Include a search input directly in the nav — discoverability is a primary UX value here

Don't

Don't substitute with generic sans-serif or serif — the custom font carries the brand

Don't use weight 700 (bold) or above — 600 is the maximum weight in this system

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 over-round buttons with pill or large radius — the system uses restrained, sharp-ish corners

Don't remove the input border — the border is the primary affordance indicator for form fields

Don't put a CTA button in the nav — this design uses links only at the top

Don't over-build the footer — this design keeps it minimal (1 cols, 0 links)
