/* Vy drawer — the one Vy surface (SON-4012). Inlined by tools/build-vy-drawer.py; edit here.

   TOKENS ONLY, NO FALLBACKS. The site is a dark theme (--bg #080A0C, --text #F4F5F2, --mineral a
   light cream). An earlier version invented token names with LIGHT fallbacks and produced dark-on-
   dark bubbles and a white composer. A fallback that is wrong for the only theme the site has hides
   breakage behind a plausible value; if a token is missing the page is already broken, let it show.

   This is a Sonsoto surface built from Sonsoto tokens. It deliberately borrows no geometry, colour,
   wording or iconography from any third-party assistant UI. */
