- src/home/pixel_composite.zig is verbatim Home image native-precision alpha
  composition at d02f7b2398b5959169d1b01e3013dd068f7e43b6. apng_compositor.zig
  reuses that implementation with only sibling import paths adapted. The Home

  It selects bounded same-clock candidate replacement masks without owning
  frames or clocks; no Home OS source is copied.

CNN tensor layout/decoder and exact typed metadata selection are copied from

Raspberry Pi CNN descriptor layouts are interface facts checked against the
upstream libcamera producer, credited in docs/cnn-outputs.md.

Sensor inference region projection and CNN KPI decoding are copied from
