/* ---- 霞鹜文楷 GB Medium — the Chinese heading face --------------------
   Georgia carries no Han glyphs, so without this the Chinese headings resolve
   to whatever the OS happens to supply — Songti SC, SimSun, or a coin toss.
   Built by `.work/harness/fonts.py`: CJK-only, so Latin inside a heading still
   falls through to Georgia, and exact-subset from the shipped copy, which is
   why it is 33 KB and why it must be rebuilt when the Chinese headings change.
   GB rather than the original: the original derives from Klee One and carries
   Japanese glyph forms for most shared characters. Declared at weight 400
   because every var(--serif) consumer is 400 — the Medium cut is there to match
   Georgia's density on a dark ground, not to serve font-weight: 500.
