/* ============================================================================
   Brute Info — css/pages/auth-recovery.css
   forgot-password.html and reset-password.html.

   These two pages sit inside the split-screen auth shell defined in
   css/pages/auth.css (loaded first): .auth-split, .auth-brand, .auth-panel,
   .auth-card, .af-* fields, .af-strength and the .auth-stagger entrance are
   all reused as they are. Nothing here restyles them.

   What is genuinely new to recovery, and therefore lives here:
     1. View swapping inside the card
     2. Confirmation artwork — animated envelope, drawn tick
     3. The reset-link block (no mail server: the link is handed over on screen)
     4. Resend control with its cooldown ring
     5. Live requirements checklist
     6. Redirect countdown
     7. Token-check placeholder
     8. Narrow-width row breaks

   Every value is a token. base.css collapses motion globally; §9 additionally
   stops the idle loops outright.
