feat: enforce CSP in debug by default with opt-out flag#1702
Merged
Conversation
Adds `CSP_ENFORCE_CSP_IN_DEBUG` (default `true`) so CSP violations break the page locally instead of only being reported. Set to `false` to keep the legacy `Content-Security-Policy-Report-Only` behavior in debug. Closes #1701 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
