chance.co is built on a mid-light canvas (rgb(224, 221, 238)).
The system uses rgb(247, 255, 1) as the high-saturation accent for primary actions.
Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Bricolage Grotesque as the primary typeface.
Bricolage Grotesque is paired with webflow-icons for secondary roles.
A layered elevation system (5 distinct shadows) building a clear front-to-back hierarchy.
Interactions are smoothed by transitions across many elements, with little or no keyframe animation.

Do's & Don'ts
20 enforceable rules pulled verbatim from the spec
Do
Use Light Gray (`#e0ddee`) as the page background — it's intentionally not pure white
Use Near-Black (`#181f18`) for text — not pure black, it's warmer and more readable
Use Bricolage Grotesque 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 #f7ff01 (`#f7ff01`) as the primary accent — it's the brand's signature interactive color
Use small 4px radius for buttons — this design system uses subtle rounding, not pill shapes
Maintain nav height at 44px — consistent vertical space for the navigation bar
Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
Each card includes a top image — imagery is part of the card identity, not optional
Show person avatars with testimonials — social proof is human-centric here
Repeat the primary CTA across 2 banner sections — conversion paths are layered, not single
Don't
Don't use pure white (`#ffffff`) as a page background — the warm tone is part of the brand identity
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
Don't make the nav sticky — this design lets it scroll away to maximize content focus
Don't over-build the footer — this design keeps it minimal (2 cols, 6 links)
