 * Two families, both OFL 1.1, both served from this repo. No CDN, no Google Fonts link, no
 * @import: the site must work offline and must not leak a visitor's IP to a third party.
 * Provenance, versions and fetch dates: ../fonts/LICENSES.md
 *
 * Load order: fonts.css → tokens.css → reset.css.
 *
 *   Archivo Variable   display + UI + body.  wght 100–900, wdth 62–125, roman AND italic.
 *   IBM Plex Mono      every label, citation, date, dataset name and section number. 400/500/600.
 *
 * Subsets: `latin`, `latin-ext` (required — the 2027–29 programme covers FR/DE/IT/ES), plus a
 * small `symbols` subset built by ../fonts/subset_symbols.py, because Google's subsets omit
 * `→ U+2192` and friends and a tofu box in "Read more →" is a shipped defect.
 *
 * Paths are relative to THIS stylesheet, so the whole `design/system/` tree can be copied
 * anywhere as long as fonts/ stays beside tokens/.
