## Title

    Proposed fix: [Zed + Amazon Bedrock] '<model> is not available in <region>. Try switching to a region where this model is supported.' — Mantle-only models (GPT-5.x, Grok 4.3) need bedrock-mantle IAM p

## Body

    Recommended action: Switch the Bedrock Region (settings or AWS_REGION) to one where the model is enabled; for Mantle models attach bedrock-mantle permissions and use a Mantle-supported Region; configure either access keys or an API key, not both.
    
    Option: Switch the Bedrock Region (settings or AWS_REGION) to one where the model is enabled; for Mantle models attach bedrock-mantle permissions and use a Mantle-supported Region; configure either access keys or an API key, not both. [evidence: official_recommended_action]
    Applies when: Selecting Bedrock models in Zed's agent, especially Mantle-routed ones
    Steps:
    1. Check model access in the Bedrock console for your Region.
    2. For Mantle models attach AmazonBedrockMantleInferenceAccess (or equivalent).
    3. Use a Region from the Mantle list (e.g. us-east-1, us-west-2, eu-west-1).
    Expected: The error no longer appears.
