/* Landing pages (SSR by src/server/routes/landing-page.ts) — standalone
 * stylesheet, deliberately outside the SPA's Tailwind bundle so the
 * Worker-rendered documents need no JS framework. Design tokens mirror
 * src/frontend/styles/globals.css (oklch neutrals, same radii) so both
 * surfaces share one visual language. Dark mode follows the OS via
 * prefers-color-scheme — no theme script, CSP-safe.
 *
 * Class prefix `mk-` keeps the namespace obvious if styles are ever merged. */
