/* Ultimate Naturabuy — the design system, from the 2026 brandbook.
 *
 * Three colour families, because the brand has three:
 *   generic  browns  — the brand speaking as itself
 *   chasse   greens  — hunting
 *   peche    blues   — fishing
 *
 * An app picks one with THEME and everything follows. The hex values are the
 * brandbook's own; do not invent new ones — the book gives Pantone, CMYK, RGB
 * and RAL for each, and a fourth value that only exists in CSS would be the one
 * that is wrong on a printed poster.
 *
 * Public Sans is the brand typeface. It is served from static/fonts as a
 * @font-face rather than from Google's CDN: these apps sit behind an
 * authenticating ingress, and a webfont request that leaves the network leaks
 * which app an authenticated user is looking at.
