16 enforceable rules pulled verbatim from the spec
Do
Use ui-sans-serif as the primary typeface — it defines the brand personality
Keep font weights between 400-500 — the system uses a narrow weight range for subtle hierarchy
Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles)
Use Near-Black (`#262626`) as the primary accent — it's the brand's signature interactive color
Use pill-shaped radius (9999px) for primary CTA buttons — the brand uses fully-rounded, pill CTAs
Maintain nav height at 63.25px — consistent vertical space for the navigation bar
Respect the 4px–48px spacing range — the design uses a wide scale for visual breathing room
Place 2 pricing tiers side-by-side on desktop — direct comparison is the value prop
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 — 500 is the maximum weight in this system
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 use rectangular buttons for primary actions — the rounded pill shape is the brand standard
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 (1 cols, 9 links)
