/* type.css — the house type system, "Didone Atelier".
 *
 * Adopted from giladkenan.art (assets/css/type.css, built by its
 * tools/build-fonts.py) so that the studio and the platform speak in one voice.
 * The faces, the weights and the stack ORDER are theirs; this file carries the
 * Latin half only, because fabricai.art ships one edition today.
 *
 * WHAT THIS REPLACED: three render-blocking requests to fonts.googleapis.com /
 * fonts.gstatic.com on the critical path, plus two preconnects. Self-hosted
 * woff2 is one origin, cached once, and cannot be taken away by a third party.
 * 183 KB of font, served from the same edge as the page.
 *
 * WHEN AiAD GOES TRILINGUAL, DO NOT INVENT NEW STACKS. Copy the he/ar blocks
 * from giladkenan.art verbatim, including their rule: every RTL stack names the
 * brand Latin face SECOND, because the Hebrew and Arabic subsets carry no Latin
 * codepoints and "RAL 9005" inside a Hebrew sentence otherwise falls through to
 * a system font and looks almost right. Their Hebrew roles: Heebo for everything,
 * headings included (his S1063 there, 10 Sep; his pick here, S440, 5 Oct). R3's
 * Frank Ruhl Libre for display is history on both sites.
 *
 * Licences and subset ranges: assets/fonts/FONTS.md (all OFL).
