+/* ── Data-viz palette (Statistics dashboard) ────────────────────────────────
+   A VALIDATED categorical palette, not hand-picked: the slot ORDER is what makes
+   it colour-blind-safe (worst adjacent ΔE 24.2 light / 10.3 dark), so never
+   reorder, recycle, or generate a 9th hue — fold the tail into "Other" instead.
+   The dark column is the same eight hues re-stepped for a dark surface, NOT an
+   automatic inversion.
+
+   --chart-1 is the DEFAULT single-series hue: a chart with one series uses it for
+   every bar. Colour is for identity, never to re-encode a length the bar already
+   shows.
+
+   --chart-seq-* is a ONE-HUE ramp for magnitude (the hour×band heatmap). On light
+   themes it runs light→dark; on dark themes dark→light, so "near zero" always
+   recedes toward the surface instead of glowing. */
