package expo.modules.persistentbackgroundlocation

/**
 * Single home for every string constant that crosses a process / IPC boundary
 * (event names, intent actions, prefs keys). Keeping them here prevents the
 * silent typo class of bug where the service emits `"onLocation"` but the module
 * listens for `"on_location"`.
 *
 * Event names and the module name are part of the public JS contract — see
 * `src/ExpoPersistentBackgroundLocation.types.ts`. Do not rename without
 * updating the TypeScript side in lock-step.
