   Little Monsters — In-Game Virtual Keyboard (steampunk dark fantasy)
   Single global keyboard surface, mounted once per page, driven by state.
   Reuses theme tokens from global-theme.css (--color-copper/bronze/brass/gold-*,
   --font-title/body) with hard fallbacks so it also works on pages that only
   load a subset of the theme.
