IMAGE_TIMEOUT_MS sets a per-attempt hard deadline (AbortSignal.timeout); IMAGE_HEDGE_MS races a second identical scene-paint request when the first is still pending past the threshold. Both default to OFF when unset, preserving historical behavior for self-hosted deploys. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
