/**
 * SUEWS Benchmark page styles
 *
 * Extends the subpage system (tokens.css + base.css + subpage.css) with the
 * components specific to a regression-benchmark results page: the verdict
 * band, the energy-balance metric table, the release-regression chart, and
 * the provenance grid. No new palette, no new type families — consistency
 * with the established suews.io system is the whole point.
 *
 * Requires tokens.css, base.css and subpage.css to be loaded first.

/* ========== Colour language ==========
 * Colour encodes MAGNITUDE, never variable identity. A single accent
 * (Sun Core orange) carries error: the more error, the more vivid the
 * fill -- on the metric bars and the heat-map cells alike. Shade is
 * normalised within each panel (the W m-2 panels and the K panel each
 * keep their own scale), so a glance shows where error is large vs
 * small. Direction of change (improvement vs regression) is the only
 * other colour meaning -- green = better, orange = worse -- and it
 * shares orange's "bad" pole, so the two readings stay harmonious.
 * Variable identity is carried by the row label, not by colour. */
