/* benchmarks/css/benchmarks-dashboard.css
 *
 * The generated libviprs benchmark page.
 *
 * The class names here are the contract this page shares with causl's
 * dashboard, frozen in libviprs-bench at tools/contract/ and pinned in
 * benchmarks/tools/config.json under `contract`: .results-table, .num, .conf,
 * .status-callout, .section-head, .absent, .swatch, and the chart classes. The
 * markup render-latest.mjs emits uses those names so the parameterised chart
 * layer attaches to a page that already says everything without it.
 *
 * What is NOT taken from upstream is the palette. causl's dashboard.css is
 * written against causl brand tokens (--causal-cyan, --surface-base, --space-*)
 * that do not exist on this site, so freezing that file here would import a
 * second design system to fight the one libviprs.org already has. The tokens
 * below are the same ones benchmarks/libvips/css/benchmarks.css uses, so the
 * two benchmark pages look like they belong to the same site.
 *
 * benchmarks/tools/render-latest.test.mjs::every_class_the_renderer_emits_is_styled
 * is the gate on that: a class the renderer emits and nothing here styles is a
 * red test rather than an unreadable table on a live page.
