Fallback errors in error metadata — When all provider fallbacks fail, the error response metadata now includes a previous_errors array showing every attempted provider’s error code, message, and name, making multi-provider failures easier to debug.
Fixed: 404 page layout — The 404 page no longer displays visual artifacts (stray borders, duplicate footer, off-center content).
Fixed: multipart/form-data error code — Sending multipart/form-data to JSON-only endpoints (e.g. speech-to-text) now returns a clear 400 Bad Request instead of a misleading 500 Internal Server Error.
Fixed: playground reasoning panel scroll — Opening the reasoning panel in the playground now scrolls to the top instead of an arbitrary position.
