/*
 * app.css — the CCML Engine dashboard design system.
 * Spec: docs/Dashboard-Web-GUI.md §3 (layout, responsive), §6 (accessibility,
 *       WCAG AA both themes), §7 (error presentation) · docs/Security.md §7.
 *
 * One hand-written file, no framework (ADR-0004). Everything is token-based so
 * the light and dark themes differ only in the token block. Dark is the default
 * (§2.6); `prefers-color-scheme` and an explicit [data-theme] both switch it.
 * Contrast pairs are chosen for WCAG AA (>=4.5:1 text, >=3:1 large/UI) in both
 * themes. All state colour is paired with a glyph + label in the markup, so the
 * palette never carries meaning alone (§6).
