/* ── Page wrapper (fills space between fixed header & footer) ──
   - min-height (not height) so tall content is never force-cropped.
   - padding-top/bottom exactly matches header/footer height, so the
     card is guaranteed to start below the header and end above the
     footer — no overlap on any page.
   - `align-items: center` then `align-items: safe center` is a
     progressive enhancement: browsers that understand `safe` will
     vertically center the card whenever it fits, and automatically
     fall back to top-alignment (scrollable, non-clipping) the moment
     the card is taller than the available space — which is exactly
     what fixes the "register card hidden behind header/footer" bug,
     for both the short login/forgot-password cards AND the tall
     registration card, with one shared rule.
   - `100dvh` (where supported) keeps mobile browsers' collapsing
     address bar from causing a jump/clip on load.
