/*
 * PokerEngine Admin SPA stylesheet.
 *
 * Tokens mirror design-system/pokerengine-admin/MASTER.md exactly.
 * Page-specific overrides (login full-page card, tables data-grid)
 * live in the same file under the `[data-state]` attribute scope on
 * #admin-app so the SPA bootstrap can switch between modes without
 * an extra stylesheet load.
 *
 * Anti-patterns enforced (per MASTER.md "Anti-Patterns"):
 *   - No light mode default — admin is dark-only by brand decision.
 *   - Gold reserved for primary CTAs + focus states only.
 *   - No emojis as icons (SVG Heroicons stroke-1.5 inline in admin.js).
 *   - cursor: pointer on every clickable element.
 *   - 180ms transitions on color/border/box-shadow only — never on size.
 *   - prefers-reduced-motion honoured at the bottom of the file.
