/* ── Alectrone.WASM (demo host) ──────────────────────────────────────────
   Host-level rules only. Every homepage style lives in the page's scoped
   CSS (Components/Pages/Home.razor.css), copied verbatim from
   Alectrone.AppComponents/AppShell/AppHomepage.razor.css.

   The homepage CSS was authored on top of Alectrone.Theme's reset and base
   layers (ux-alectrone.css). Those two layers are reproduced below so the
   demo lays out identically without shipping the whole theme bundle, which a
   page with no Alectrone controls on it would never use. They stay inside
   @layer, exactly as the theme does, so the page's own (unlayered) scoped CSS
   always wins.
