/* theme.css * * Dark-theme palette for ALL pages, switched by theme.js via * . Light theme = the existing styles untouched * (no [data-theme="light"] rules needed). * * Strategy: * 1. Override the CSS variables styles.css already defines — every rule * that uses var(--bg-card) etc. flips automatically. * 2. Targeted overrides for the major shared surfaces (nav, cards, chat, * inputs, tables, modals). * 3. Catch-alls for inline-styled white surfaces (style="background:#fff") * that JS-injected components use — attribute-substring selectors with * !important so they win over the inline style. * 4. Chart bodies stay as LIGHT islands: LIDA PNGs are white images and * ECharts text is drawn for light backgrounds, so charts remain * readable instead of becoming dark-on-dark. * * Load AFTER styles.css / the page's inline
