No code changes -- investigation/verification only. Injected a raw SGR
escape sequence over the serial socket at the ok> prompt (composed from
EMIT + ." since no FORTH word emits a literal ESC byte + text
directly): 27 EMIT ." [95mCOLOR-TEST" 27 EMIT ." [39m", bright magenta
(the p>=90&&p<=97 branch in apply_sgr()), a third SGR code path
distinct from 4.4h's already-verified truecolor prompt.
Screendump on all three architectures confirms COLOR-TEST renders in
bright magenta via the 4.4j-retargeted TTF draw call, proving the SGR
parser and the new glyph backend work together end-to-end, not just
independently. First screendump evidence ever captured for
aarch64/riscv64 in this document -- every prior screendump item was
amd64-only with that gap explicitly accepted; incidentally closed here
via the QEMU monitor screendump command against each arch's own
display device (ramfb for aarch64/riscv64). Both confirmed booting at
800x600.
