Punch list §25 item 4.3.6c complete. Digits, upper/lowercase, ASCII
punctuation, Latin-1 Supplement, and General Punctuation, each a
stroke-drawing word in the 4.3.6 em-square convention.
Corrected mid-build: the first pass used G-LINE only, missing that
CIRCLE/ARC/ELLIPSE already existed (4.3.3b). Reworked all round shapes
to use them via new em-square-aware wrappers (G-CIRCLE/G-ARC/G-ELLIPSE/
EM-R, fabric.4th 5000-5002), bounded to quarter/half/three-quarter/
full sweeps to avoid unbounded per-glyph angle tuning. font.4th also
redefines DISPATCH-GLYPH/DRAW-GLYPH themselves, not just the six
DISPATCH-* bucket words, since fabric.4th's originals were compiled
early against the 4.3.6b placeholders (CASE early-binding, §27.6.5).
Three-arch acceptance boot clean, Stadium conservation unchanged.
