rendu réel · source de vérité

tanstack.com is built on a pure-white canvas (rgb(253, 253, 253)). The system uses rgb(115, 115, 115) as the singular interactive color. Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Inter as the primary typeface. A layered elevation system (16 distinct shadows) building a clear front-to-back hierarchy. Motion is a first-class concern — 17 keyframe animations plus transition-driven interactions.

Do's & Don'ts

14 enforceable rules pulled verbatim from the spec

Use Pure White (`#fdfdfd`) as the page background — it's intentionally not pure white

Use Near-Black (`#171717`) 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 Slate Grey (`#737373`) as the primary accent — it's the brand's signature interactive color

Use 6px border-radius on buttons — the standard corner rounding for interactive elements

Respect the 4px–53px 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

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-build the footer — this design keeps it minimal (1 cols, 10 links)
