/* Procurement Auctions — base stylesheet.
 *
 * Design tokens (colours, fonts, radii) live in /theme.css, served from
 * branding.toml. This file holds layout rules only; every brand-bearing value
 * is a CSS custom property. Rebranding is a configuration + asset swap.
 *
 * The visual language targets enterprise industrial sites: narrow radii, dense
 * tables, generous whitespace at the section level, muted neutrals, high-
 * contrast CTA. No gradients, no decorative shadows beyond the token.
