// Why: the telemetry transport is gated by two compile-time constants that
// only the official CI release workflow sets. Contributor / `pnpm dev` /
// third-party rebuilds must substitute literal `null` at these sites so
// `IS_OFFICIAL_BUILD` in `src/main/telemetry/client.ts` evaluates `false`
// at module load and the track() wrapper short-circuits to console-mirror.
// The substitution happens at compile time — there is no runtime env-var
// fallback — so a curious contributor cannot spoof transmission with a
// shell export.
//
// CI injects real values via GitHub Actions secrets
// (ORCA_BUILD_IDENTITY='stable' | 'rc', ORCA_POSTHOG_WRITE_KEY=phc_...);
// every other build path resolves these env vars to undefined, which the
// JSON.stringify below folds to the literal `null`. Ambient declarations
// for the two constants live in `src/types/build-constants.d.ts`.
