/* CareWatchTrack landing page — editorial design language.
   Mirrors the design tokens, palette and surface treatments used by the
   WASM console (rpm/WebApp/wwwroot/css/editorial.css + auth.css) so the
   marketing site and the product feel like one continuous surface.

   Theme: html[data-theme="light" | "dark"] is set by a pre-paint boot
   script in index.html. All colors are derived from the tokens below
   so flipping the attribute reskins the whole page without a re-mount. */
