prisma.io is built on a pure-white canvas (rgb(255, 255, 255)).
The system uses rgb(90, 103, 216) as the accent for primary actions and brand signals.
Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside monaSans as the primary typeface.
A layered elevation system (4 distinct shadows) building a clear front-to-back hierarchy.
Motion is a first-class concern — 39 keyframe animations plus transition-driven interactions.

Do's & Don'ts
17 enforceable rules pulled verbatim from the spec
Do
Use Secondary Foreground (`#1d242f`) for text — not pure black, it's warmer and more readable
Use Inter as the primary typeface — it defines the brand personality
Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
Use Indigo (`#5a67d8`) as the primary accent — it's the brand's signature interactive color
Use small 2px radius for buttons — this design system uses subtle rounding, not pill shapes
Keep navigation sticky to the top — the design uses a persistent navigation pattern
Maintain nav height at 96px — consistent vertical space for the navigation bar
Use a single primary CTA in the hero — the design intentionally avoids choice paralysis
Make the navigation sticky — it stays visible during scroll, signaling content depth
Each card uses an icon (not photo) — the visual language is illustrative, not photographic
Place 2 pricing tiers side-by-side on desktop — direct comparison is the value prop
Don't
Don't use pure black (`#000000`) for text — the near-black adds warmth
Don't substitute with generic sans-serif or serif — the custom font carries the brand
Don't invent new shadow values — use only the extracted shadow levels
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 collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
