 * fonts-local.css — self-hosted font faces for the CN build.
 *
 * Mirrors, weight-for-weight and style-for-style, the two origins stripped
 * from index.html by scripts/postbuild-cn.js for the China build
 * (fonts.googleapis.com / fonts.gstatic.com and cdn.jsdelivr.net), so no
 * mainland-China-blocked origin is referenced by the CN bundle.
 *
 * Files are latin-subset woff2, downloaded from google-webfonts-helper
 * (https://gwfh.mranftl.com) for DM Sans / Instrument Serif / JetBrains Mono,
 * and from the jsdelivr @fontsource/metropolis@5.0.3 package CSS for Metropolis.
 * All files live in this same directory (frontend/public/fonts/).
