/**
 * Sanity tests for the web file editor route.
 *
 * Visual correctness (CodeMirror 6 syntax highlighting, CDN loading) is
 * manually verified. These tests cover:
 *
 *   1. Module shape — the default export is a Hono router.
 *   2. Auth guard  — unauthenticated GET to the edit form redirects to /login
 *      or returns an auth-related error status.
 *   3. The AI commit-message endpoint is still reachable (auth guard only —
 *      full coverage in editor-ai-commit.test.ts).
