/**
 * access.css — WaveCtl access experience (/login/).
 *
 * Shared presentation for the three access screens:
 *   index.php   — RACE OPERATIONS   (access path selection)
 *   admin.php   — RACE DIRECTOR     (control access)
 *   zone.php    — ACCESS GATEWAY    (unified passkey gateway)
 *
 * Full-screen operational environment. No floating card, no SaaS chrome.
 * The viewport itself is the interface: strong typography, generous
 * negative space, restrained cyan accent, subtle structural rules.
 *
 * Reads every colour, font, radius and spacing value from the tokens
 * defined in style.css / brand.css, so a client theme in brand.css
 * flows through automatically.
 *
 * All three screens adopt the athlete door's visual language:
 *   · section 14 — shape and spacing (uppercase titles, soft radial
 *     glow, the door's underline inputs and pill CTA)
 *   · section 15 — the door's accents (amber eyebrow, pill CTA with
 *     the arrow and soft glow, event-block footer)
 * Every flow, DOM id and AJAX contract is untouched.
 *
 * None of the three screens carries a brand rail: the identity block
 * IS the header, as on the athlete door. The .access-brand rules
 * remain (unused) for any future screen that wants a rail.

       Director door's one distinguishing cue.
     · index.php's path cards keep the door's rounded card shape
