/*
 * Billet — main stylesheet.
 * Design tokens use space-separated "R G B" triples. Always consume them
 * with the modern `rgb(var(--x) / alpha)` slash syntax — the old comma-style
 * alpha function (with an "a" suffix) is invalid here, missing the required
 * comma-separated channels, and gets silently dropped by the browser.
 *
 * Palette: dark steel/graphite base (near-black charcoal, gunmetal, cold
 * steel-blue) with a hot ember orange/red accent used sparingly for CTAs
 * and highlights. The accent is pulled from the real blackbody heat-color
 * narrative the hero and the heat-color chart tool both use: a bright
 * ember orange near the ideal ~950-1100 deg C heavy-forging range, with a
 * deeper dull-cherry red (~700-800 deg C) as the secondary/hover step down
 * — not an arbitrary brand orange.
 *
 * Type scale: perfect-fourth 1.333 ratio, 7 sizes. Spacing: the same
 * 4px-based scale used across the catalogue (8/12/20/32/56/96). Headings
 * use Oswald (condensed, technical/engineering-drawing character); body
 * copy uses IBM Plex Sans (clean workhorse sans).
