/* dashboard-chrome.css -- shared header + footer for all in-repo lab dashboards.
 * Spec (ticket #936): consistent chrome across claude_usage,
 * status_public_dashboard, internal_status_page. The page-body styling and
 * theme tokens stay per-dashboard; this file only owns header/footer layout +
 * typography. Tokens (--bg, --bg-card, --border, --text, --text-muted,
 * --blue/--accent) are expected to be declared by the host dashboard's
 * stylesheet via :root, in line with GitHub-dark.
 *
 * Header layout:
 *   .chrome-header
 *     .chrome-title-block        (left)
 *       h1.chrome-title          (bold)
 *       p.chrome-subtitle        ("Updated HH:MM:SS")
 *     .chrome-controls           (right, flex row, gap 0.5rem)
 *       <custom controls slot, e.g. range select>
 *       button.chrome-refresh-btn
 *       span.chrome-countdown    ("Next: Ns")
 *
 * Footer layout:
 *   .chrome-footer
 *     .chrome-footer-left        ("Last refresh: HH:MM:SS")
 *     .chrome-footer-right       ("Auto-refresh: Ns")
 *
 * Hosts that need to fall back to existing class names (e.g. countdown,
 * refresh-btn, last-updated) can keep them as additional classes on the
 * same node -- chrome rules target .chrome-* so they layer cleanly.
