// data-paths.mjs — the pure path-resolution core, shared by the desktop app
// (via data-paths.ts, a typed re-export) and the CI smoke driver (which runs
// under Node's type-stripping and therefore cannot import the app's
// extensionless TypeScript directly). No Electron imports here; only node:path.
//
// data-paths.ts re-exports these names and adds the TypeScript-facing
// `HermesHomeOptions` interface. Keep the two in lockstep: every behavior in
// this file is exercised by data-paths.test.ts through the re-export.

import path from 'node:path'
