emu860c gains a C-side write-watch (watch_add/watch_drain: watched ranges
log (addr,val) into a ring buffer at negligible cost). frames.py runs the
cap7 mission on the C core, drains the DMA queue-page writes at each
receive->receive draw span, reconstructs the frame's SEND payloads from
live C memory, dispatches the GPU tile shader per TILE entry, and
accumulates interlaced fields. Result: the complete SMPTE test card
(frame_0004) -- 6 draw frames in 2.0s including boot; the content draws
alternate 25-tile fields with eof/present passes, matching the hardware
cadence.
