/*
 * Burrow: plain CSS, embedded assets, no build step.
 * Tokens, shell and shared components. Page composition lives in
 * pages-issues.css (issue list, issue detail) and pages-admin.css
 * (projects, settings, auth, error).
 *
 * Type: five sizes only (--fs-1..--fs-5 = 13/14/16/20/32px). Sans for UI and
 * prose; IBM Plex Mono only for code, culprits, IDs, DSNs and figures.
 * Colour: red means fatal, regression or destructive, nothing else.
 * Fox: brand mark, empty states, auth/error pages and the search dig. Nowhere else.
 *   --fox (rust) belongs to the fox alone; it never marks state or severity.
 * Activity bars: .barcode > .bars > 14 span.bar.h0/h5/.../h100 (height classes,
 * never inline styles; strict CSP).
