/* FILE: public/assets/css/dashboard.css
 *
 * The dashboard has to pass its own scanner, so the accessibility-relevant
 * choices are deliberate rather than incidental:
 *
 *  - :focus-visible is always drawn, never removed (WCAG 2.4.7 / 2.4.11)
 *  - body text is 16px minimum and reflows to 320px without horizontal scroll
 *    (WCAG 1.4.10)
 *  - severity is never signalled by colour alone — every badge carries a label
 *    (WCAG 1.4.1)
 *  - all foreground/background pairs below meet 4.5:1 in both schemes
 *  - prefers-reduced-motion is honoured (WCAG 2.3.3)
 *  - the skip link is visible on focus, not permanently hidden (WCAG 2.4.1)
