/* ── Punktfunk brand · violet product chrome ────────────────────────────────
   Two themes on one violet identity: LIGHT (lavender docs surface — the same
   palette the design/Scalar reference uses: white bg, faint-violet cards/borders,
   #6c5bf3 brand) is the :root default; DARK (the violet-tinted app-icon chrome
   #141019 / #1c1530, #a79ff8 brand) is the `.dark` override. The live console
   pins `<html class="dark">` so it stays dark by default — removing or toggling
   that class (e.g. Storybook's theme switch) yields light. The token set feeds
   BOTH @unom/ui's semantic contract (--brand/--primary/--accent/--neutral/
   --main…) and the shadcn-style tokens the console's primitives + routes use
   (--background/--card/--muted…), mapped onto one palette so both render the
   same identity.

   Brand constants and the surface tokens that are pure indirections
   (--main, --neutral*, --error → other tokens) live in :root only — CSS resolves
   var() per-theme at use time, so .dark overrides just the raw values. */
