/* Chinese on the CRT screens: Fusion Pixel 12px (simplified). One font pixel is 1/12 em, VT323's is about 0.08 em, so
   at 96 % the two pixel grids match at any font size. Only CJK ranges come from it: Latin, digits and symbols stay
   VT323 / Departure Mono. The hardware labels (IBM Plex Mono, 10-14 px) keep the system CJK font: a 12 px pixel font
   shrunk below its own size turns to mush. The file is a subset (GB2312 + the repo's own CJK, ../subset_font.py); a
