# Builds the JS side of packages/quantus-crypto.
#
# Not `polkadot-dev-build-ts`, because that tool returns early for any package
# not named `@polkadot/*` — twice, in `buildJs` and when collecting `locals` for
# import rewriting. Renaming the package into someone else's scope to satisfy a
# string check would be worse than not using the tool.
#
# Nothing is lost by that: this package needs none of what the tool adds (a deno
# variant, a rollup bundle, cross-package import rewriting, generated exports
# maps). It is four TypeScript files and two generated artifacts. Keeping it out
# also means `yarn build:js` stays byte-identical to upstream's behaviour, which
# is the rebasability convention in quantus/extension#1.
#
# ESM only. The consumers — quantus/common and the extension — are ESM, and the
# wasm-bindgen glue is ESM-only, so a CJS variant would mean either a second
# generated glue or hand-written marshalling. See quantus/wasm#1 before adding one.
