/* ============================================================================
 * code-stats — shared styles
 *
 * Tokens follow the design audit + golden screens:
 *  - Geist (sans + mono) loaded via <link> from each HTML page.
 *  - Two modes: light (default :root) + dark (html.dark).
 *  - WCAG 2.2 AA palette; body text targets 7:1 contrast in both modes.
 *  - Curated 8-color data palette for charts and badges.
 *
 * Existing class names (.btn, .card, .topbar, .field, .stat, etc.) and
 * variable names (--bg, --surface, --text, --accent, ...) are preserved
 * so this file is a drop-in visual upgrade — HTML pages don't need to
 * change shape.
