/* Atrium — frosted glass floating in a warm, softly lit room (after a "glassy dashboard" in the visionOS manner).
   The page is a soft, warm room painted in CSS (a bright window and lamp light on a sand wall — no photo), the
   content sits in one big pane of frosted glass with lighter glass cards on it, charcoal and white pill controls,
   coral and charcoal for figures. The header is a floating glass bar with a greeting and a glowing "ask" orb;
   station pages are a column of round glass keys and a floating pill dock (theme-atrium.js). By night the same room
   with the lamps on. Glass is backdrop-filter over a still backdrop; motion is transform / opacity only. */
