  /* System Japanese font stacks — no self-hosted JP webfont on purpose:
     Noto Sans/Serif JP full charset runs tens of MB per weight, and every
     real JP user device already ships a native serif/gothic pair
     (Hiragino on macOS/iOS, Yu Gothic/Mincho on Windows, Noto Sans JP on
     Android/ChromeOS) — self-hosting would only serve a redundant,
     heavier duplicate. This is the more authentic, and stricter-offline,
     choice: zero font network requests at all, not even to a local
     woff2 that still costs load time. */
