/* ==== Section 39 — r25y24dg START (font-fallback: single-source override) ==== */
/*
  Single-source override for thefastfile/thefastimg hosted @font-face
  rules. Each family below was previously loaded from an external host
  that 403s from our HK ECS, blocking render until font timeout (~15-20s)
  on CN /about/ etc. We re-declare each family with `src: local(...)` so
  the browser finds a system fallback immediately and never issues the
  external request.

  Discipline: this is the ONE place we fix Dongli-native CSS issues.
  Do NOT edit per-page /css/*.min.css or /assets/css/*.min.css; those are
  one-shot exports that regenerate whenever the site-builder exports, and
  any regex edit we make there will be lost and/or have subtle side
  effects (see r25y24df → AlphaScan visual regression, 2026-04-22).
