Failed to parse JSON from player texture

Error message

Failed to parse JSON from player texture: {0}

What it means

Thrown by TextureError in the Mojang authentication flow when the base64-decoded player texture payload cannot be parsed as JSON, i.e. the textures property in the authenticated game profile is corrupt or not a valid JSON object.

Solutions

1. Continue login with default textures
2. Log the JSON parse error with the player name for diagnosis
3. Validate the decoded payload against the texture JSON schema

When it happens

Trigger: Thrown at crates/pumpkin/src/net/authentication.rs:421 when the library encounters an invalid state.
