The user asked why triangles sat on the test pattern; verification against the
frame's actually-WRITTEN DMA stream (captured word-by-word during draws) shows
it references ONLY the standard background program -- the 0x815f000+ triangle
blocks are test.egg's 3D scene content, precompiled in DRAM but never
referenced by this frame's chains (my loose memory scan misattributed them).
The live frame = SMPTE colour bars, now rendered bars-only (paint_bars.py) and
matching the user's reference card. Readout §06 corrected: bars frame + honest
note about the undrawn DRAM-resident scene data.
