/* Landing page (index.html) styles.
 *
 * Tokens (--bg, --panel, --line, --fg, --accent, ...) come from report.css —
 * include both: <link rel="stylesheet" href="_shared/report.css">
 *               <link rel="stylesheet" href="_shared/style.css">
 *
 * This file adds index-specific layout (search box, filter chips, report cards)
 * on top of the shared design tokens, so the index respects the same light/dark
 * theme as the reports.
