Recommended action: Choose one: remove the middleware and send `fallbacks` with the server-side-fallback-2026-07-01 beta header, or omit `fallbacks` and let the middleware handle fallback client-side. Do not share fallback state between handlers.
Option: Use exactly one fallback mechanism [evidence: official_recommended_action]
Steps:
1. Server-side: remove middleware, add beta header server-side-fallback-2026-07-01 and fallbacks param
2. Client-side: keep middleware, drop fallbacks param
Expected: Request proceeds
