/*
 * CostWorkX marketing site.
 *
 * Hand-written, no build step. The CSP in marketing/vercel.json is
 * `style-src 'self'` with no `unsafe-inline`, so there are no <style> blocks
 * and no style="" attributes anywhere — everything lives here.
 *
 * Two rules that are not preferences, both from measured contrast:
 *   - orange is a MARKER, never a button. White on #FF5A1F is 3.12 and fails AA.
 *   - --muted (#8A8378) is never body copy. It is 3.33 on the screen surface.
 * Use the semantic variables in tokens.css and the pairing is right by default.
