# receipts), joule_moq_web_e2ee (the same, and the member of an end-to-end encrypted room)
# and wai_live_web (the room's records, layout and mixer), each through wasm-bindgen's web
# target. The same files on every platform: an archive for any of them carries this
# directory as share/wai/web/.
#
# Needs the wasm32-unknown-unknown target and the wasm-bindgen CLI at 0.2.127, the version
# both crates pin. Run from anywhere; CARGO_TARGET_DIR is honoured.
