Drawn from this instance, never from a CDN: the callback replaces twemoji's default `base` +
size + extension entirely, so the `src` is the whole path and nothing upstream is contacted for
it. `vite.config.js` puts the SVGs at `/_assets/svg/twemoji/` — copied into the build output,
served out of `node_modules` in dev — so the two have to agree on this path.
The artwork comes from the same upstream project as this parser, at a pinned tag (see
`twemoji-assets` in `package.json`). They are separate dependencies, so the build checks that
every emoji a page can hold still resolves to a file — an emoji the parser knows and the asset
set does not is a broken image in a page.

* running the parser over it yields exactly the set of files a page can ask for.

* Makes the twemoji SVGs reachable at `/_assets/svg/twemoji/<codepoints>.svg`, which is the `src` the

*
* They are neither committed nor imported: the set is ~4000 files and 18 MB, every one of which a page
* may ask for and none of which is a build input -- nothing in the source names an individual icon, so
* Vite has no way to discover them. So they are copied into the build output alongside `public/_assets/`
* and read from `node_modules` on the fly in dev; under `public/` they would be 4000 files in git for a
* directory that is derived.
*
* `@twemoji/api` is the parser alone -- the artwork has never been published to npm, by Twitter or by
* the fork that maintains it now, and the one package that did (`@twemoji/svg`) stopped at Unicode 15.
* So `package.json` takes it from the upstream repository at a pinned tag, as a tarball dependency
* (`twemoji-assets`). npm records its integrity hash in the lockfile like any other dependency, so it
* is fetched once at install time and the build itself needs no network.
