/* ===========================================================================
   LOS — public landing page (route "/") only.

   Everything here is scoped under `.los` so it can't leak into the app or the
   other marketing pages, which keep using marketing.css. The palette follows
   the same --sl-accent* custom properties LandingLayout emits, so the page
   still respects the user's chosen accent; the rest of the surface is a fixed,
   near-black "operating system" canvas rather than the MudBlazor background.

   Motion contract: every element that animates on scroll carries
   [data-reveal] and is revealed by js/landing-fx.js adding .is-in. Without
   JavaScript (or with prefers-reduced-motion) the fallbacks at the bottom of
   this file leave the whole page visible and still.
   =========================================================================== */
