Build-time tenant config via VITE_TENANT env var (--mode loop42/dev).
Content pages moved to tenants/{name}/pages/ with dynamic imports and
loop42 fallback. Feature-gated routing (viewer/devTools per tenant).
Dockerfile parameterized with TENANT build arg. Deployed to separate
K8s namespaces: loop42.de → ns/loop42, loop42.dev → ns/dev.
