/* ============================================================
   VEXT LABS — the lab expression · vextlabs.css
   One system, two expressions. JUWEL is Liquid Candy at full
   volume; the lab is the same tokens INVERTED: paper and ink,
   serif-led display, hairlines, one gem (amethyst), near-still
   motion. The receipt is the shared artifact across both.
   Loads AFTER juwel-ds.css + juwel-liquid.css and re-voices them.
