Next.js 16 replaced middleware.ts with proxy.ts

In Next.js 16, middleware.ts is gone. The replacement is proxy.ts at the project root, exporting a function named proxy(request) and a config.matcher, and it runs on the Node runtime rather than Edge. The matcher is read statically at build time, so it cannot reference an imported constant.

three.js r152 re-tints every colour written before it

Since three.js r152, ColorManagement.enabled defaults to true, so new THREE.Color(0xADC1DE) converts sRGB to linear before reaching the shader. Red loses proportionally more than blue, so colours picked against older releases drift violet. Nothing errors — the scene simply renders a different colour than the hex you wrote.
