SvelteKit + @sveltejs/adapter-node = "Attempted to access a server-side environment variable on the client"

[arkmech]

1. In, svelte.config.js, using @sveltejs/adapter-node as adapter.
2. Run vite build, generates build directory with SvelteKit handlers
3. @t3-oss/env-core ./src/env.ts, where createEnv is setup.
4. Two places use env.ts: ./src/lib/server/index.ts (express server) and ./src/lib/server/payload/payload.config.ts,
5. Run using cross-env PAYLOAD_CONFIG_PATH=./src/payload.config.ts tsx watch ./src/lib/server/index.ts

I have just had lots of issues doing this an example repo would be nice.
