   PF DESIGN SYSTEM — Self-hosted web fonts  (PL-1, 2026-09-08)
   ────────────────────────────────────────────────────────────────────
   Replaces the Google Fonts CDN <link> the layouts carried (Inter /
   Source Serif Pro / JetBrains Mono). Same families and the SAME faces
   the CDN actually delivered, now served from this origin: no
   third-party request, no IP logging (GDPR — Danish market), works
   offline, and the CSP no longer admits the two Google font origins.
   docs/design/ADMIN-DESIGN-SYSTEM-PLAN §B5 "Fonts".

   FILES  wwwroot/fonts/<family>/ — each directory ships its OFL.txt;
   version / source URL / sha256 per file in wwwroot/lib/LICENSES.md.
     inter/InterVariable.woff2                    Inter 4.1              wght axis (variable)
     source-serif-4/SourceSerif4-Semibold.woff2   Source Serif 4.005R    600
     source-serif-4/SourceSerif4-Bold.woff2       Source Serif 4.005R    700
     jetbrains-mono/JetBrainsMono-Regular.woff2   JetBrains Mono 2.304   400
     jetbrains-mono/JetBrainsMono-Medium.woff2    JetBrains Mono 2.304   500
     archivo/archivo-latin[-ext]-wdth-normal.woff2       Archivo v25      wght + wdth axes (CORP-6)
     public-sans/public-sans-latin[-ext]-wght-normal.woff2 Public Sans v21  wght axis (CORP-6)

   CORP-6 (2026-10-12) — Archivo + Public Sans are the "corporate" font pair of
   the tenant website font choice (feature.website.webfonts.v1). Tenant sites
   load this sheet ONLY while that flag is ON and the tenant picked a pair, so a
   site on the template default never gets 'Inter' defined and renders as before.
   These two come as the Google Fonts latin / latin-ext subsets (fontsource
   5.3.0 build, unmodified; neither family has a Reserved Font Name), split by
   unicode-range: Danish, Swedish and Norwegian are in the latin file; the
   latin-ext file is fetched only for text that needs it. No italic faces —
   the browser synthesises, as for the families above.

   WHY EXACTLY THESE FACES (weight audit 2026-09-08 — matching stays
   identical to what the CDN served, so rendering does not change):
     • Inter — the CDN served ONE variable file for wght 400/500/600/700;
       so does this sheet. The descriptor is clamped to 400–700 so any
       other weight snaps exactly as before (300 → 400, 800 → 700).
     • Source Serif — the CSS asks for 500/600/700, but the legacy CDN
       family ("Source Serif Pro") has no 500: only 600 + 700 were ever
       delivered and 500 resolved to the 600 face. Same two faces here.
       Declared under BOTH names — 'Source Serif 4' (canonical, plan §B5)
       and 'Source Serif Pro' (what --platforma-font-serif and ~20 legacy
       rules name). Identical URLs → one download.
     • JetBrains Mono — 400 + 500 (the two faces delivered); 600/700 keep
       synthesising bold from Medium as before.
     • No italic faces were ever loaded (browsers synthesise) — unchanged.

   SUBSETTING — none. fonttools/pyftsubset is not available on the build
   host, so the OFFICIAL release woff2 files ship unmodified (full
   charset: Latin, Latin-ext incl. æøå äö ü ß, Greek, Cyrillic, …).
   Unmodified files also stay clear of the OFL Reserved-Font-Name clause
   ("Source" is an Adobe RFN — a subset is a Modified Version and would
   have to be renamed internally). Follow-up: pyftsubset to Latin +
   Nordic, keep sha256 provenance, rename Source Serif in the name table.

   CACHING — the URLs carry ?v=<upstream version>: Program.cs serves any
   static asset with a v= query as `public, max-age=31536000, immutable`
   (RR.3). Bump the version here AND in the layouts' <link rel="preload">
   (they must be byte-identical URLs or the preload is fetched twice).

   LOADING — font-display: swap (text is never invisible). The layouts
   preload the hero files with crossorigin: fonts always fetch in CORS
   mode, so a preload without it is a wasted, duplicated request.
