/* Cross-platform fonts. The CJK chain previously relied on
   "Songti SC" / "STSong" which only ship on macOS + iOS — Android
   visitors got the OS default (Noto Sans, sans-serif) and lost the
   vintage feel entirely. Noto Serif SC + Cormorant Garamond load
   the same elegant rendering everywhere via Google Fonts. The
   display=swap parameter lets the system font paint immediately
   and swap to the webfont when it lands, so phones on slow
   networks still see content during the loading window. */
