// Type declarations for the dependency-free setup helpers in setup-lib.mjs.
// The browser setup wizard server (src/bridge/setup-api.ts) imports this module
// at runtime from BOTH the dev (ts-node) and dist layouts via the relative path
// `../../scripts/setup-lib.mjs`, which resolves to <root>/scripts in either
// case (Codex P2 #7). These types let TypeScript check that usage.
