Experience Builder Sites and LWS
If LWS is enabled in an org that contains Experience Builder Aura sites, LWS protects Lightning web components and Aura components in the Aura sites.
LWS protects Lightning web components and Aura components in LWR sites too. However, LWR sites have their own instance of LWS that isn’t affected by the org’s LWS setting.
For more information, see Develop Secure Sites: CSP, Lightning Locker, and LWS in the Experience Cloud Developer Guide.
