/* Advento eglutė — /advento-eglute (Pages/Advent). Port of the approved C1X prototype.
   Every class is .advent-*; site classes (glass-card, bp-countdown-*, action-btn, modal-footer-modern)
   are reused by name, never copied.

   Layout follows the scene's own width through container queries, not the viewport: with the fixed
   sidebar, a viewport breakpoint would still pick three columns when the middle one is too narrow
   for the tree. Inside the tree, --u is one unit of its 680 x 800 drawing, so baubles, strings and
   labels scale with the tree and the phone sizes fall out on their own.

   Sole font-size exception: bauble glyphs (number, day badge, tag) are artwork sized in --u, so they
   shrink with the tree. Every other text size is a Bootstrap utility in the markup. */
