/**
 * Fase 14.3.6 — guard the version.ts barrel against accidental
 * tree-shaking / undefined replacement.
 *
 * Vitest doesn't run through Vite's `define`, so the `__APP_*`
 * globals don't exist in this environment. We stub them via
 * `vi.stubGlobal` to mimic what `vite build` (and `vite dev`)
 * inject at build/dev time.
 *
 * The point of the test is two-fold:
 *   1. The module re-exports the three globals as an object so
 *      consumers never reach for the `__APP_*` symbols inline.
 *   2. None of the three exports collapse to `undefined` or the
 *      sentinel `'dev'` when the build-time substitution is
 *      working — that's the canary for an accidental tree-shake
 *      that would silently break the version chip in production.
