/* ── CAPTIVE PORTAL ──────────────────────────────────────────── */
/* Static gate page: opaque, fills viewport, locks body scroll while open.
   Inner container handles overflow so tall content (registration form +
   SSH instructions + reconnect banner) stays usable on small viewports. */
/* Mobile gate-bypass fix (2026-05-08): four hardening changes against
   the iOS Safari keyboard-induced bleed-through where Tier 1 challenge
   content was visible underneath the gate-overlay when a registration
   field was focused (root causes: dashboard rendered behind the overlay,
   100vh winning over 100dvh on keyboard open, .gate-bg-logo at 60vh
   exceeding viewport width on tall phones).
   1. Hide all dashboard structural content while gate is locked — no
      bleed-through possible if there's nothing behind the overlay.
   2. height:100vh first then 100dvh — dvh wins on supporting browsers
      and shrinks with the soft keyboard; vh stays as the legacy fallback.
   3. overflow-x:hidden explicit on html+body when gate-locked — defense
      in depth against any other lateral overflow source.
   4. .gate-bg-logo size constrained below so it can't force horizontal
      page overflow on tall phones. */
