/* DisEASE public-site shared brand stylesheet.
 *
 * Consumed by the flat static pages served from public/ (epic.html; future
 * flat pages should link it too). Tokens mirror the shipped brand exactly:
 * src/app/globals.css (--brand-primary family), src/app/HomePage.module.css
 * (hero gradient), and src/proof/ProofPage.module.css (canvas / ink / muted /
 * hairline, eyebrow + chip treatments).
 *
 * proof.html deliberately does NOT link this file: it is a Vite single-file
 * artifact (proof-export/) whose private twin must open from file:// fully
 * offline, so its styles stay embedded. Keep these tokens in sync with the
 * sources above if the brand changes.
