Enable the recommended preset and fix or per-line-disable the 78
findings it surfaces. Most are equivalent rewrites, intentional
patterns (control chars, the whatwg email regex, autolinker URL regex)
keep their behavior via targeted disables.
Prune the back-edge components from cyclic composite glyphs in
sanitizeGlyphLocations (leaving non-cyclic siblings intact), reject OS/2
tables whose length is too short for the declared version so a clean
table gets regenerated, and upgrade a version 0.5 maxp table to 1.0 for
TrueType fonts to silence OTS' "wrong maxp version for glyph data".
It fixes#21298.
