// Package buildinfo exposes the build-time version metadata injected via
// -ldflags "-X vocat/internal/buildinfo.Version=... -X vocat/internal/buildinfo.BuildTime=...".
// It is imported by the server (to report version through /api/system/info),
// the CLI subcommands (vocat version / update), and the self-updater (to
// compare the running build against a GitHub release).

// sentinel when no -ldflags override is supplied.
