/* ============================================================================
   Pro UI — LOCKSCREEN surface (restyle of the existing #auth-gate PIN gate).
   Scope: EVERY selector is under `body.pro-lock` so nothing applies until the
   flag adds that class (window.proFlag('lockscreen') → body.classList.add).
   Uses ONLY var(--pro-*) tokens from pro-tokens.css. No external assets.
   Canon: A.I Vault/J-Bot/J-Bot Pro Surface Blueprint.md + lockscreen.html mock.
   ============================================================================ */
