/**
 * 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    — JUDGE ACCESS      (unified judge 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.
