/* ============================================================
   NUK v3 — "Ledger & Thread", modernized
   Same class names + same grounding (loom indigo / jute kraft /
   signal thread), executed with a more contemporary hand:
   soft elevation instead of hard offsets, generous spacing,
   smoother motion, refined radii. Drop-in — zero HTML changes.
