 * Shared reference-fixed ADMIXTURE PCA panel styling (chart container, controls, legend note,
 * closest-references table and fullscreen mode). Colors are driven by --pca-* CSS variables so
 * each report theme can override them; the defaults below fall back to the regional report's
 * --rr-* tokens where present, and to the gold theme otherwise (matching Iberian/Celtic).
 * Per-report overrides (e.g. Viking's blue theme) set --pca-accent/--pca-accent-light on a
 * report-scoped selector in that report's own view CSS.
