about
nx_apng_decode_gate.nx -- prove animated-media INGEST (roadmap R1): encode known frames -> decode -> BIT-EXACT
recovery (the encoder/decoder invert), and decode a REAL APNG we shipped (synth_wolfwalk.png) -> right frame
count + dims. This is "ingest video/gif/image -> frames", the front door of video->pose->motion. expect_exit:0
