/* ============================================================
   CULMEN — dark. Deep ink, cyan that actually glows.

   PALETTE NOTE — the tokens are still NAMED --violet because they
   are consumed by ~40 rules across four files. The VALUES are the
   house cyan family, matching the management panel and the
   subscriber portal. Renaming the tokens is a separate job; do it
   in one pass or not at all.

   Three tones, deliberately distinct. Collapsing them to one hex
   flattens the whole page — learned the hard way on the portal:
     --violet-hi   bright   small text, eyebrows, links, marks
     --violet      mid      lines, dots, glow sources, brand fills
     --violet-fill deep     large filled areas   (set in -tune.css)
     --violet-deep deepest  gradient partner     (set in -tune.css)

   Anything filled with the MID tone carries --on-brand DARK ink,
   never white. White on bright cyan is ~1.4:1 and unreadable.
