/**
 * 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.
