//
// METRICS CARDS — light
// =====================
// Per-metric cards on the page detail "Metrics" tab. Currently used by:
// - Long Animation Frame entries (LOAF) — 5-phase stacked bar + script
//   attribution
// - Interaction to Next Paint (INP) — hero latency number + event metadata
//

//
// LOAF — palette per timing phase. Keep these distinct enough to read in
// the stacked bar and the legend swatches without relying on hue alone.
//
$loaf--blocking: #b91c1c;        // red — the "bad" portion (input-blocked)
$loaf--work: #d97706;            // amber — script work
$loaf--render: #16a34a;          // green — rendering
$loaf--pre-layout: #0095d2;      // brand blue — pre-layout overhead
$loaf--style-layout: #7c3aed;    // violet — style + layout
