archive/frontend/package.json:2

• [nitpick] The package.json name 'fastapi-react' doesn’t indicate that this is archived code. Consider renaming it (e.g., 'fastapi-react-legacy') to clearly mark this folder as a legacy archive.

"name": "fastapi-react",

archive/frontend/README.md:1

• [nitpick] This README describes the legacy Create React App setup. Adding a clear header or note that this directory is archived and not actively maintained would help prevent confusion.

This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).

README.md:80

• The snippet for creating a .env file isn't properly fenced. Use triple backticks with the language identifier (e.g., ```bash) so the code block renders correctly in markdown.

`bash

Looks good. I like representing the requirements in stages.

Do we need to keep the old frontend around? It seems to be just a template.

True, it's in the history anyway. Will remove.
