/* Entrance hall / landing hub — styles specific to index.html.
   The site header/nav/login-bar stays in the shared light burgundy theme (style.css tokens,
   untouched here). Only the hub's own content, wrapped in <main class="hub-main">, gets this
   theme: deep wine ground with a radial highlight, gold accents -- the same wine/gold family
   as the shared masthead, since this page IS effectively the front door of the site rather
   than a themed tool page that needs to read as visually distinct from the masthead. */

/* Full-bleed pattern (see CLAUDE.md): same token block on body:has() and the wrapper class,
   since body is an ancestor and can't read a descendant's custom properties. Without this the
   shared light :root --bg-page shows as margins outside .container's 1200px cap on wide
