igc_conformance.py pins the reference behaviour any port (RTL/GPU/C) must
reproduce: the DUMP packet parse, a synthetic raster, the bars pipeline
(texu==x+2 from the real cap7 tile programs), and the fxtest effect
primitives (coverage + z pinned) -- fixtures committed under conformance/.
GPU-RETARGET.md maps the DOSBox-renderer path: EMC tile as compute shader
(pixel=thread), 4 milestones, conformance-gated.
