composio.dev is built on a pure-white canvas (rgb(246, 246, 246)).
The system uses rgb(255, 255, 255) as the singular interactive color.
Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside abcDiatype as the primary typeface.
AbcDiatype is paired with abcDiatype Fallback for secondary roles.
A layered elevation system (5 distinct shadows) building a clear front-to-back hierarchy.
Motion is a first-class concern — 9 keyframe animations plus transition-driven interactions.

Type — the ladder, in the real face
4 roles · rendered live in the real Inter (captured woff2) · lines are editable, click any spec to copy
Respect the 4px–48px 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
Include exactly 2 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
Repeat the primary CTA across 3 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 increase letter-spacing on headings — the type is designed to run tight at scale
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 make the nav sticky — this design lets it scroll away to maximize content focus
