/* ── Pascaline IA — this product's own palette ───────────────────────────────
 *
 * The ten `--color-brand-*` primitives `src/styles/tokens.css` declares, in this
 * product's own values. The contract — why only the primitives, why the
 * `html.dark` block is repeated, and why this link has to be last — is in
 * `frontend/README.md`, which also carries how these values were arrived at.
 *
 * This file is served to a visitor verbatim: no ticket numbers, and keep it
 * short. It ships in the image as the default a tenant's mount overlays.
 *
 * Brass and ink, after the brass calculating machine of 1642 and the paperwork
 * it was built to carry. Warm on purpose — the neutral scale underneath it is
 * warm, so a cool navy would fight it.
 *
 * Every value is measured against the dozen contrast requirements the token
 * wiring implies; `--color-brand-secondary` is the tight one, because it is a
 * fill on light and link text on dark at the same time.
