Security & Performance

A comprehensive `.dockerignore` is your first line of defense. It prevents sensitive keys (`.env`, AWS credentials) from being permanently baked into your image layers.

It also drastically speeds up BuildKit context transfers. Ignoring huge folders like `node_modules` or `.git` saves gigabytes of I/O during the `docker build` phase.
