/* Compassionism Simulation: shared styles for the findings components (v5.2.1, Oct 2026).
 * Used by index.html (guided sections), findings.html (the explorer) and replication.html (the summary panel). Everything is scoped under .fx so it
 * cannot restyle the pages' own content. Colours: series and severity palettes validated with the dataviz skill's validator (colour-blind separation,
 * contrast) on the light surface and on the dark one; light and dark follow the reader's system setting, as the pages already do. */
