/* ============================================================================
 * lumen-dark.css — global dark mode for CrossAIHub.
 *
 *   Yousef Q3 decision (B with strict contrast): a global dark mode that
 *   keeps everything legible. WCAG 2.1 AA requires ≥ 4.5:1 for body text,
 *   ≥ 3:1 for large text. We hit AAA (≥ 7:1) on every primary text/bg pair.
 *
 *   The toggle is in the social bar (sun / moon). State is persisted in
 *   localStorage under key "crossaihub:theme" by lumen-dark-toggle.js.
