      description: |-
        Base response model for any endpoint returning a signed URL.

        All API responses that include a signed URL should either:
        1. Inherit from this model, or
        2. Include these three fields with the exact same names and types

        This standardization enables:
        - Consistent client-side handling of signed URLs
        - Predictable refresh logic based on url_expires_at
        - Type-safe URL caching in SignedUrlCacheImage
