/*
  Inspiration Board — /inspiration-board/ only, loaded after site.css.

  The behaviour is ported from docs/inspiration-board-source.html; the styling isn't.
  Every colour, font, size and radius below is a site.css token (or the black/white
  overlays the site already uses), so the board reads as part of the site — the
  prototype's own palette and fonts were placeholders and are gone. Classes carry an
  ib- prefix because site.css already owns .tabs, .hero and similar names.

  Almost every couple opens this on a phone, so the base rules are the 390px layout
  and the 720px block adds the desktop changes (docs/inspiration-board-SPEC.md §8.8).
*/

/* ===== Gate ===== */
/* A remembered code opens the board straight away; the inline check in the template
   hides the gate meanwhile so a return visit doesn't flash it. The script lifts this
   either way, and the animation brings the gate back regardless after 4s — nothing
   here may be able to hide the page for good if the script never runs. */
