/**
|
||
|
|
* Consumer-strict smoke for `@shade/files`.
|
||
|
|
*
|
||
|
|
* Compiled with `lib: ["ES2022", "DOM"]` + `exactOptionalPropertyTypes` +
|
||
|
|
* `skipLibCheck: false` to mimic a downstream consumer like Dispatch.
|
||
|
|
* Catches the class of bug where our internal narrower types (e.g. a
|
||
|
|
* locally-defined `MinimalReader`) reject native browser types
|
||
|
|
* (e.g. `ReadableStreamDefaultReader`) the consumer would naturally
|
||
|
|
* pass in.
|
||
|
|
*
|
||
|
|
* If this file fails to compile, the published packages will fail in
|
||
|
|
* any consumer's strict tsc — pre-publish gate must catch it.
