// web entry. no installed binary exists on web, so only the marketing
// version comes from the build-time manifest value one injects as a
// ONE_APP_VERSION define (see one-define-environment in one/vite). the read
// is a literal member expression, like ONE_APP_NAME elsewhere: vite define
// replaces only the static process.env.ONE_APP_VERSION text, so a dynamic
// lookup would stay null. build and application id have no honest web
// value, so they are null, never guessed. unset outside a one web build,
// where every field stays null. signatures stay identical to the native
// entry because the published declarations are built from this file and
// serve both platforms.
