/* Room-illustration homepage redesign. Ported from _reference/makerspace-final.html.
   Loaded sitewide via head.html, so every bare-tag selector (*, body, html, a, img) from the
   original spec is deliberately scoped under the new homepage-only section IDs below —
   porting them unscoped would break Bootstrap spacing/link/image styling on every other page
   (resume, publications, single project posts). Class-based selectors (.section, .pcard, etc.)
   are new, sitewide-unique classnames only used by the new partials, so they're left as-is. */

/* this file only loads on the homepage (see index.html) and after rover-rail.css (see
   head.html source order), so it's the right place to retheme the sitewide rover-rail to
   the room's purple/gold palette instead of its generic --text-color/--primary-color
   fallback. Declared on body (not :root) to match where rover-rail.css declares its own
   defaults — a body-level declaration here beats an inherited :root value regardless of
   source order, but for two declarations on the SAME element (body), source order decides,
   and this file loads later. The rover's wheel/panel fills derive from --rover-ink
   automatically (see rover-rail.css), no override needed here. */
