/*
 * components/server_metrics_panel.css — 24-hour detailed metrics panel.
 *
 * Paired with templates/server_dashboard.html (the <dialog#metrics-panel>)
 * and static/js/server-metrics-panel.js. Token-driven (D5). The dialog
 * opens at 90% of the viewport; Chart.js renders the 24h line chart
 * inside; an external HTML tooltip shows value + time on hover, positioned
 * at the top of the panel so it is always in the viewport and outside the
 * chart area (D9: Escape closes the dialog natively).
