/*
 * fonts.css — self-hosted @font-face declarations for the redesigned site.
 *
 * Phase 1 (2026-05-18): file exists but is not yet linked from any template
 * (Phase 2's new base.html will <link> it). Inter and Space Grotesk files are
 * already on disk under shared/src/web_public/static/fonts/; JetBrains Mono
 * files are procurement deliverables for Phase 1 (see procurement note below).
 *
 * Naming convention matches existing files: lowercase, hyphenated, subset
 * suffix. Variable-weight axis baked into one file per subset, no per-weight
 * file split. See phase-1-foundation.md §2.1.
 *
 * Cache-busting: served from /static/public/fonts/*.woff2 with long max-age
 * (immutable via filename → no Cache-Control hash needed; we only re-deploy
 * when fonts genuinely change).
 *
 * --- JetBrains Mono procurement note (Phase 1 implementer) ---
 * Source: https://github.com/JetBrains/JetBrainsMono/releases
 * License: OFL 1.1.
 * Required subsets:
 *   - jetbrains-mono-latin.woff2          (basic Latin)
 *   - jetbrains-mono-latin-ext.woff2      (Latin Extended)
 *   - jetbrains-mono-cyrillic.woff2       (OPTIONAL — drop if >20KB, see P1.B)
 * Procedure (per phase-1-foundation.md §2.1 and PLAN.md §5.1):
 *   1. Download JetBrainsMono variable-weight TTF or static Regular+Medium.
 *   2. Subset to unicode-range using glyphhanger or pyftsubset, output woff2.
 *   3. Place files under shared/src/web_public/static/fonts/.
 *   4. Verify file sizes; drop cyrillic subset if it adds >20KB.
 *   5. curl -sI https://dev.taktext.com/static/public/fonts/jetbrains-mono-latin.woff2
 *      returns 200 after dev deploy.
 *
 * The @font-face blocks below assume the files exist. Until JetBrains Mono is
 * procured the browser will 404 on the URL; this is harmless in Phase 1
 * because no template links this stylesheet yet.
