   MySchool.Life — production site stylesheet
   Tokens: palette "06 Graphite & Gold" + type "T2 Modern Registrar" (Bricolage
   Grotesque / Source Sans 3 / JetBrains Mono). 06 is 05 Highlighter retuned for a
   dark-led site — lifted graphite ground, muted gold accent (Dennis 2026-09-04;
   projects/msl/MSL-WWW-DESIGN.md D3 / §3.6 records the history and how to revert).
   Rebrand = swap the :root token blocks — plus the four <meta name="theme-color">
   pairs, js/theme.js THEME_COLOR and delete-me/index.html, which cannot read a CSS
   variable (all listed in §3.5).
   Theme: light on :root; dark via prefers-color-scheme (unless data-theme=light)
   and via data-theme=dark. Components never name a colour directly.

/* ---- self-hosted fonts ------------------------------------------------
   Served from this origin, NOT fonts.googleapis.com. Google's domains are
   blocked in mainland China, and the stylesheet <link> was render-blocking:
   a dropped (not refused) connection left the page BLANK until the browser
   gave up — measured at >120 s, not a graceful fallback. Self-hosting also
   removes an undisclosed transfer of every visitor's IP to Google.

   All three families are SIL Open Font License 1.1 (see fonts/OFL-*.txt).
   Each file is a VARIABLE font: one file per subset covers the whole weight
   range, which is why `font-weight` below is a range, not a single value.
   That is also what gives us JetBrains Mono 600 — previously requested as
   400;500 only, so the 600 uses were being faux-bolded by the browser.

   Downloaded from Google Fonts 2026-09-05, unmodified, unicode-range
   subsetting preserved exactly as Google served it.
