// SvelteKit defaults kit.version.name to Date.now() and derives the
// __sveltekit_<id> global it embeds in dist/index.html from it, so two builds
// of identical source differ. dist/index.html is committed -- it is embedded
// into the server binary at configure time, which is what lets the project
// build a working server without a JavaScript toolchain -- so any two branches
// that rebuild the web UI conflict in it whether or not their source changes
// overlap.
//
// Naming the version after the UI package makes the bundle a pure function of
// the source tree. Keep webui/native/package.json's version in step with the
// release it ships in; nothing derives it automatically, because audio.cpp's
// own version is tag-driven (AUDIOCPP_VERSION is passed at configure time and
// is not committed anywhere in the tree).
//
// Note that this is an identifier, not a live update channel: the app never
// imports SvelteKit's `updated` store, version.pollInterval is left at its
// default of 0, and the single-file bundle ships no _app/version.json for the
// client to poll. A stale version here costs nothing but a stale label.
