/*
 * auth_gate.css — single source of truth for every staff PIN-entry gate.
 *
 * One consistent, high-contrast LIGHT theme shared by all gates
 * (admin hub, bookings console, validate, QR codes, sales, booking sheets).
 * The gate is a full-screen position:fixed; inset:0 overlay, so this light
 * palette renders correctly even over the dark bookings console.
 *
 * WCAG AA contrast (all on #ffffff card):
 *   heading  #1a202c  ~15.9:1
 *   subtext  #475569  ~7.9:1
 *   button   #ffffff on #534ab7  ~6.4:1
 *   error    #c0392b  ~5.5:1
 *
 * Loaded AFTER style.css (and any page-specific CSS) so it wins on link order.
 * Selectors are scoped to .auth-overlay to beat unscoped rules in style.css.
