   -------------------------------------------------------------------------
   Loaded only by the home page (HomeController passes it as a per-page style).
   Night sky from the companion's world, a luminous level line, the week as a
   lit timeline, dawn after the weigh-in, then warm paper. See the header of
   app/Views/home.php for the idea and the rules.

   Public pages are always light-themed in the app's sense (no data-theme), so
   every color here is art direction, defined once below.

   Animations always run: there is deliberately no prefers-reduced-motion
   override anywhere in this file (owner decision, October 2026).
