Next.js 16 Focused Pack

Next 16 files that match the current names — not last year’s middleware.ts.

proxy.ts, awaited params, clocks that tick after paint, auth kept out of the root layout.

• The file names Next 16 actually loads
• Params that resolve before you read them
• No clock mismatch on first paint

Add MEDTEK once. Then describe the work. The AI loads this pack while it writes. Files stay on your computer.
