usage: cargo xtask <command>

commands:
  assets          every image/icon/font/media file is attributed in assets/ATTRIBUTION.md; no Adobe assets
  bench [FILE] [--strict] [--threshold PCT]
                  run the render benchmark, append to target/bench/history.jsonl, compare CPU time with
                  the previous run (default input: corpus/raw/arw-sony-a7m3-compressed.arw)
  ico <out.ico> <in.png>...
                  pack square PNGs (<= 256 px) into a Windows .ico (see packaging/icons.sh)
  layers          enforce the crate dependency layering (plan/architecture.md §3)
  parity [--write]
                  check docs/parity-checklist.md (every cmd:/ctl: id and path it cites exists) and print the
                  Lightroom parity summary; --write refreshes the summary table in the document
  wasm            cargo check --target wasm32-unknown-unknown for the wasm-safe crates (+ the web app)
  web [--serve [port]] [--dev]
                  build the browser app (apps/lightcraft-web) into <target>/web-site/;
                  --serve serves it on http://127.0.0.1:<port> (default 8080)
  ci              fmt --check, clippy -D warnings, heif, test, parity refs, layers, assets, wasm (stops at first failure)
  corpus [--download]
                  show where test corpora live; --download fetches PngSuite and CC0 raw samples (raw.pixls.us) into corpus/ and checks their sha256
  stats [--exact] count tests and lines per crate (--exact: ask the test harness via `-- --list`)
