    3D product imagery, meta-optics and metasurface diagrams, conference and event photography, leadership headshots,
    logos and press assets, each with its generated size variants (418 attachments at capture). Anonymous access
    is read-only: the collection answers `Allow: GET` without credentials. Write methods exist on the same routes
    but require WordPress application-password authentication and are not part of the public surface.'
