   auth_modal.css — Phase 6 authentication modal
   Completely isolated from styles.css — no shared selectors.
   All rules prefixed with .auth- or #auth- to avoid any conflicts.

   Class contract (set by auth_modal.js):
     .auth-overlay.open      → visible
     .auth-tab.active        → selected tab
     .auth-panel.active      → visible panel
     .auth-msg.error/.success → message state
