@claude what are the performance implications? it reads from .env, so it's not really dynamic in the sense it can change whenever, only on initial server load

Performance Analysis

You're absolutely right to question this! The performance implications are minimal in your use case. Here's why:

What connection() does

The connection() call forces Next.js to opt into dynamic rendering for this layout, which means:

• The page is rendered on each request rather than statically at build time
• This allows the runtimeConfig object (lines 72-108) to be evaluated fresh on each request

Performance Impact

In your Docker deployment context:

• Negligible overhead - The .env values are read once when the Node.js process starts (not on every request)
• No database queries or external API calls - The connection() call itself just waits for request headers to be available
• Memory impact: ~0 - The environment variables are already in process memory
• CPU impact: Minimal - Just object construction with string assignments

What actually happens:

1. Container starts → Node.js loads .env into process.env (once)
2. Each request → connection() ensures dynamic rendering → runtimeConfig object is created from in-memory values
3. The "dynamic" part only means the values can differ between container deployments, not between requests

Why this approach makes sense

For Docker deployments with prebuilt Next.js apps:

• Without connection(): Environment variables are baked into the JavaScript bundle at build time
• With connection(): Environment variables are read from the container's environment at runtime

This allows the same Docker image to be deployed with different configurations (dev/staging/prod) without rebuilding.

Alternative approaches (for comparison)

1. Build-time substitution - Would require rebuilding the image for each environment (not ideal)
2. Client-side fetching - Would add actual network overhead and complexity
3. This PR's approach - Best balance: dynamic per deployment, but static per container lifecycle

Bottom line: The performance cost is essentially the same as constructing a JavaScript object with ~10 properties on each request - completely negligible compared to the flexibility gained for Docker deployments.

Correct approach, merging here.
