/* ---------------------------------------------------------------------------
 * app.css — the single source of design tokens and layout primitives.
 *
 * Before this file, every page inlined its own :root block and two divergent
 * dark themes had already appeared. Pages now carry only page-specific rules.
 *
 * The chart surface is --panel (#161b22). The categorical palette below was
 * validated against exactly that surface and passes all six checks:
 *   node scripts/validate_palette.js \
 *     "#3987e5,#d95926,#199e70,#c98500,#d55181,#008300,#9085e9,#e66767" \
 *     --mode dark --surface "#161b22"
 * Changing --panel invalidates that result — re-run the validator if you do.
 *
 * Dark-only is a deliberate commitment. A light mode would need its own
 * selected-and-revalidated steps, never an automatic flip.
