  (the files here are byte-identical to those; the build script asserts
  6500 distinct single characters)

Order: the table lists characters by stroke count, not by frequency.
char_order.txt holds the frequency order used for slicing (columns: character,
Google Fonts band, corpus count). Sort key:
  1. the 300 characters most used in this repo's corpus (git-tracked
     frontend/src, frontend/docs, references/, SKILL.md), so the astrology
     vocabulary of headings sits in the first slices;
  2. then the Google Fonts Simplified Chinese frequency band (0 = most
     frequent; 99 = not in the 20 frequency bands);
  3. then corpus count, then table order.

Google Fonts frequency bands (derived data only; the source file is not committed):

  CJK slicing data of the Google Fonts project; its first 20 subsets are
  "FreqRange" bands in descending frequency (the file header says so).
