trekframe.py parses the captured payload blocks (0x100 headers, rowid words
0x300|row, packed edge fields) into per-scanline spans and composites them onto
an 832x512 canvas -- 21 blocks / 124 spans from the trek demo's compiled stream:
distinct multi-colored objects + slanted band elements. dumppay.py dumps the
payload region at chosen draws (scene verified byte-identical draws 1-300 =
compile-once static showcase). Readout gains §06 with the frame rendered from
the span data. First-approximation decode (edge-field scaling still being
pinned) -- but every mark is a span the firmware's rasteriser emitted.
