ModuleOrchestrator already discovers SlpModularCms.Modules.*.dll from disk at startup via reflection, so this needed no code change — only a persistent location (mirroring shared/wwwroot-web) that survives release swaps, and a deploy-scp.yaml step to symlink its contents into each new release before restart.

# with "No such file or directory": dotnet publish only emits a wwwroot/ folder at all when the

# source project has one with actual content, so a release built before any frontend content
