# retroDE_ps2 — Ch340 host gate. No board, no real dump needed (uses content-clean synthetic
# fixtures). Proves: (1) byte-exact container/GIF parse, (2) census classifies supported vs
# unsupported, (3) the translator emits a ps2_feeder scene for supported input that the Ch339
# encoder accepts, and (4) fail-closed on unsupported input.
