   labels at 10–12px, which is the type this site asks a reader to trust:
   consent lines, table headers, captions, chips, meta rows. Uppercase mono
   strips the ascender and descender cues that make a word recognisable, so it
   needs more size than lowercase body text, not less.

   Deliberately exempt, and why:

     .tui *, .statusbar    terminal emulation — resizing breaks ASCII alignment
