### Removed

- The Python prototype (`wai/`) and Python BD-rate harness (`bench/`).
  v0.2.x's hand-rolled wire format is dead; Rust is the single source
  of truth.
- The `webm_lottie_new/wai-rs/` pre-pivot Rust crate (Wasm-decoder-in-
  bundle model). Replaced by the clean `wai-rs/` SOTA-wrapper crate.
