/* ── Closed Beta Terms & Conditions Gate ──────────────────────────────────
   Second, separate full-screen gate shown AFTER the password gate succeeds.

   .beta-badge / .beta-gate-body / .beta-welcome / .beta-instruct /
   .beta-footer / .beta-link directly, so it's a pixel-perfect match to the
   password gate's styling with no duplicated rules. Only what's actually
   new — the scrollable terms text and the agree checkbox — gets its own
   classes below. Unlike the password gate, this one is NOT persisted: it is
   shown fresh on every page load. */

/* DEFENSIVE FIX: .beta-gate-box (shared with the password gate, where it's
   intentional — clips the corner gradient/animation on short content) sets
   overflow:hidden, which silently overrides .modal-box's own
   overflow-y:auto and defeats scrolling for the much longer terms content.
   .terms-scroll-box above is meant to be the thing that actually scrolls,
   but this makes the OUTER box scrollable too, scoped only to the terms
   modal via #terms-gate-backdrop — so the whole modal can always be
   scrolled to reach its content even if something about the inner box's
   sizing doesn't come out as expected on a given screen. Belt and braces:
   there should never be a way for this modal's content to become
   unreachable. */
