Punch list §25 item 4.3.7c complete. ttf_rasterize_glyph() flattens quadratic-Bezier contours (fixed 8-segment subdivision, matching CIRCLE/ELLIPSE's fixed-segment precedent) and fills them into a caller-supplied bitmap via even-odd scanline fill, no AA. A local signed Q48.16 multiply (q48_smul) handles negative outline coordinates, since the shared q48_mul/q48_div are unsigned-only. Verified two ways: tools/ttftest.c's ASCII-art dump + structural checks for 'A'/'.'/'a', all recognizable and passing; and a live amd64 screendump via a throwaway TTF-PROBE word (loaded the font capsule, rasterized 'A', blit via fb_put_pixel), showing a clearly legible 'A' on the CANVAS -- probe reverted immediately after capture, only the permanent ttf.c/ttf.h rasterizer remains. Compile-checked clean on all three architectures (hal/*.c wildcard); this item's own acceptance is the amd64 screendump, not a three-arch boot (that's 4.3.7f).

capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.

Block namespace
Block ranges are shared across all loaded capsules — collisions cause silent word-definition overwrites.
