/* =============================================================================
   vault-legal-acceptance
   -----------------------------------------------------------------------------
   Compact checkbox row used at signup to record the user's acceptance of the
   Terms (AGB) and Privacy Policy (Datenschutz), plus a self-contained modal
   overlay that previews each legal document inline (iframe). Designed to fit
   the dark auth card in the side panel, PWA, and 320 px extension popup.

   - The row sits between the password input and the Sign-up button.
   - The modal floats above everything (z-index very high) and is fully
     keyboard accessible (close on backdrop click, ESC, X button).
   - Visual language matches the existing auth card: slate-800/600/400 tones,
     emerald accent on focus, small font sizes for compactness.
