/**
 * Strict in-app redirect parser used by Next Auth UI routing.
 *
 * Relative paths only. Rejects protocol-relative URLs, absolute URLs, and
 * backslashes. Distinct from session-bridge `resolveSafeRedirectTarget`
 * (`./athena/session-bridge`): that helper always returns a string, keeps
 * search/hash via `URL`, and stays a published compatibility contract.
