   Single source of truth for tokens + component classes used across every
   canvas. Author screens by composing these classes; never hand-roll colors.
   Theme is set per-frame with .theme-light / .theme-dark on .tf-frame.
   Rules: Inter only · radius 8 · border-first (1px hairline) · no in-UI shadow
          · rhythm 24 / 16 / 12 · Light + Dark both mandatory.
