/**
 * Visual identity for evidence charts (Tableau-inspired):
 * neutral gray = context (all marks / in-range records),
 * one fixed accent = the selected mark / the spotlighted records.
 *
 * The accent is intentionally independent of the host chart theme — evidence
 * charts are analysis UI, not user visualizations, and a stable
 * gray-vs-accent contrast keeps their semantics readable on any theme.
 * Both colors are chosen to work on light and dark backgrounds.
