/* ──────────────────────────────────────────────────────────────────────────
   Auth pages (login + register) — split brand panel layout.

   Left: a deep-green panel with a slow animated gradient (no image, so there
   is nothing to upload, nothing to load and nothing to go stale).
   Right: the form card on a calm off-white field.
   Below 1024px the panel collapses into a short header strip above the card.
