## What to do
Playwright driver downloads 400ing through the CDN redirect (playwright.azureedge.net redirecting to the microsoft.com host) was a CDN-side problem, confirmed resolved in the thread. If your playwright install fails with a 400 GatewayExceptionResponse from the CDN, retry before debugging your setup; these download CDN issues have been transient and fixed server-side.
