/* benja-finance — CFO Dashboard  v2.2.0
 *
 * Mobile-first, RTL, zero dependencies.
 *
 * Colour is assigned by job, not by taste:
 *   - series-1 / series-2  categorical identity (income vs spend). Validated as a
 *                          pair against BOTH surfaces: CVD ΔE 26.8 dark / 24.7
 *                          light, normal-vision ΔE 31.8 / 33.6.
 *   - status-*             reserved for state (good / warning / critical) and
 *                          never reused as a series colour.
 * Status hues are mode-invariant and sub-3:1 on the light surface by design, so
 * every status mark ships with an icon AND a label, and all text wears text
 * tokens — colour never carries meaning on its own.
