/*
 * Sudiko web — layout and components (SUD-049).
 *
 * Every colour, space, radius, font and duration is a var() from the generated tokens.css; a
 * colour literal here fails `node tools/build-tokens.js --check`. The layout follows the frames
 * drawn by figma/website/code.js (1440 desktop, 390 phone).
 *
 * `--type-scale` mirrors the app (DESIGN.md §5.3): display/title/heading shrink on narrower
 * screens and never below 18 px; reading text does not scale. Nothing is upper-cased by a case
 * transform: it turns Turkish `i` into `I`, not `İ` (tools/web-site.test.ts refuses one).
