19 enforceable rules pulled verbatim from the spec
Do
Use Hof (`#222222`) for text — not pure black, it's warmer and more readable
Use Airbnb Cereal VF 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 Rausch (`#ff385c`) as the primary accent — it's the brand's signature interactive color
Use 32px border-radius on primary buttons — the brand uses generously-rounded CTAs
Maintain nav height at 80px — consistent vertical space for the navigation bar
Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
Make the hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
Build the hero as a split layout with media on the right — text and visual share equal weight
Include exactly 15 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
Each card includes a top image — imagery is part of the card identity, not optional
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 use sharp-cornered or pill buttons — 32px is the CTA border-radius 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
