/**
 * Access Control page — scoped styles
 *
 * Loaded by hifocus_access_assets() on the single access-control-solutions
 * solution post only, with hifocus-main as its declared dependency.
 *
 * The page reuses main.css components wholesale — sw-hero, sw-crumbs, sw-band,
 * section-head, sw-module (the delivery cards), product-showcase-grid,
 * venue-grid/venue (the SHARED sector cards, section 13.1 of main.css), sw-faq
 * and cta-panel. This sheet adds only the patterns main.css has no equivalent
 * for:
 *
 *   1. .ac-hero__grid      — hero graphic overlay + the hero highlight line
 *   2. .ac-cred            — THE FOUR CREDENTIALS, icon-led cards (light band)
 *   3. .ac-deliver--featured — the full-width permission-structure card
 *   4. .ac-equipment__more — the centred "browse all" action
 *   5. .ac-hw              — the door hardware cards (light band)
 *   6. .ac-process         — the four-step timeline (dark band)
 *   7. .ac-crosslink       — the credential/barrier/record panel
 *   8. .ac-contact         — the contact grid inside the closing CTA
 *
 * Every rule is scoped under .access-page, so no other page is affected. All
 * colours, radii, spacing and easing come from the existing :root tokens.
 *
 * THE VENUE CARDS ARE NOT HERE. They are the shared .venue-grid / .venue
 * component in main.css, which the CCTV page introduced and this page was the
 * second user of. Do not copy them into this sheet.
 *
 * ON THE DUPLICATION WITH turnstiles-speed-gates.css / wifi-solutions.css
 *
 * .ac-process, .ac-crosslink and .ac-contact restate shapes those sheets
 * already define as .tg-*, .wifi-* and .net-*. Same position as the note in
 * turnstiles-speed-gates.css: those rules are scoped under another page's class
 * and cannot be reached from here without editing a sheet that serves a live
 * page. A fourth page now shares them, which strengthens the case for lifting
 * the common set into main.css the way the venue cards just were — but with all
 * four pages open, deliberately, not as a side effect of adding this one.
 *
 * .ac-cred is genuinely new: an icon-led chooser card, where every other card
 * grid on this site is either image-led or a plain glass panel. See section 2.

 * 1. Hero — graphic overlay and highlight line
 *
 * NO HERO PHOTOGRAPH, and no background-image hook for one. The hero is
 * single-column: main.css collapses .sw-hero__inner through
 * :not(:has(.sw-hero__visual)), and this page never prints that div. The
 * only product photography on this page is in the catalogue grid — supplier
 * cutouts on white, which against navy would read as white rectangles.
 *
 * The overlay motif is a door threshold — two uprights and a lintel, repeated
 * and masked from the top — rather than the Turnstiles page's lane verticals or
 * the CCTV page's technology grid.

 * trailing row that does not fill the track count reads as deliberate when it
 * is centred and as a mistake when it is left-aligned. Five products today go
 * four across and one centred beneath; eight fill two rows.
