MUI

You're working with MUI. Material-design React components, battle-tested in enterprise.

Best practices:
- Lean on: enormous component set
- Lean on: well-documented
- Lean on: enterprise support

Things to watch for:
- Watch out for: heavy bundle
- Watch out for: opinionated look

General guidance:
- Canonical docs: https://mui.com — check here before inventing APIs.
- Keep secrets in environment variables, never commit them.
- Write TypeScript where the ecosystem supports it; add types to every exported function.
- Add tests for the critical paths before declaring the task done.
- Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
