/* ============================================================================
 *  theme.css — design system for team.raevolution.com
 *
 *  ONE file holds:
 *    - All design tokens (colors, spacing, radii, shadows, animation timings)
 *    - Typography (Inter font, type scale, heading rules)
 *    - Base component styles (cards, buttons, inputs, tables, flashes)
 *    - The animation/transition layer
 *    - Toast notifications
 *    - prefers-reduced-motion fallback
 *
 *  Page-specific styles still live inside their own .php files, but pull
 *  from these tokens via the CSS variables defined in :root below.
 *
 *  Linked from header.php and login.php as:
 *      <link rel="stylesheet" href="/theme.css">
