Detailed Description

Whole transcode state (module-static instance in the producer TU).

One static instance mirrors the decoder pattern; every sized buffer inside is a bump carve out of the caller's arena. Shared with the WebP arm, which binds geometry and feeds rows through the same state so its atlas bytes are identical to the streaming path.

Invariant
band_fill <= tile_h and tiles_done <= tile_count.

0.1.0
