/* Kitchen Vision — public site.
 *
 * One external stylesheet, deliberately. It means the CSP can be
 * `style-src 'self'` with no hashes and no 'unsafe-inline', which in turn
 * means no `style="..."` attribute anywhere in the HTML — a strict CSP blocks
 * those too. Presentation attributes on SVG (fill, stroke) are not affected
 * and are used instead.
 *
 * Palette values are the ones already validated in src/api/static/dashboard.html,
 * so the marketing page and the product look like the same company.
 * --muted is deliberately NOT used for body text: it is ~2.8:1 on the light
 * plane. All secondary text uses --text-secondary (~7.5:1).
