/*
 * metrics.css — Host Resources cards, sparklines, progress bars, and
 * the 24h chart dialog (Session 2; ai-monitor metric-card pattern).
 *
 * Consumes tokens.css custom properties only — no palette values here
 * (adding a color means adding a token). Class names follow the
 * ai-monitor BEM-ish scheme (metric-card, metric-spark) so the port
 * stays recognizable against the reference.
