/* =========================================================
   ACCESS MODAL — shared module v1
   Self-contained styles for the invite-only private beta
   application modal. Mounts on any page via access-modal.v1.js.
   Cache-busting strategy: filename-hashed (v1 → v2 on any
   visual/behavioral change). See todo/access-modal-inventory.md.

   Scoped CSS variables under .pb-modal ensure the modal renders
   identically regardless of host page tokens. Defaults match the
   home page's :root values at extraction time so Phase 2 parity
   verification is bit-for-bit.
