/* ============================================================================
   Pro UI — Settings surface (#pro-settings).
   Scoped ENTIRELY under #pro-settings so nothing collides with chat-slim.css's
   generic classes (.card/.row/.head/.body/.rail/.mode/.key/.link/etc.).
   Uses pro-tokens.css vars only — no hardcoded palette, no external assets.
   Ports A.I Vault settings.html look onto the live chat-slim daily driver.
   Shown by toggling [hidden] via the activeSurface state (operator wires JS).
