/* =====================================================================================================================
   LL-UI: the shared pieces of the site's new pages (2026-10-03). Code/ui/README.md is the contract.
   Hayden, 2026-10-03: "Build the site. build LustLit into the porn site of the future. Sleek, supreme, modern,
   futuristic." Crunchyroll's LAYOUT (a hero carousel, rows, tiles), LustLit's LOOK (design-system.md).

   One owner (the video session); the home page (the Read/Watch session) and the Series pages use the same file, so the
   two read as one site. Everything here is .llui-*; page-specific styles live in the page's own file (.llh-*, .lls-*).

   THE RULES IT KEEPS (design-system.md, site-art.md):
   - dark; #ef4444 is the accent and the only red type; #c41e3a only as a fill; every number white;
   - a glow is filter: drop-shadow(), never box-shadow;
   - every picture is shown WHOLE, in a box of its own shape (--ar = width / height). Nothing scales a picture (a zoom
     crops its corners, the watermark's included): a hover LIFTS the tile and draws the seam instead. Nothing is
     ever put over a picture's bottom-right corner (badges sit bottom-left);
   - no eyebrow over a title: pills go UNDER it;
   - reduced motion: no slides, no springs, no autoplay; fades of 150 ms or less.
