Wrote most of the code by hand.

My own design:

- config/state/msg/update/effects, all the types
- which hooks to use
- remote/request/result
- splitting the codebase into modules/folders/files

LLM-generated:
where I mostly reviewed

- The Material UI / styling - after using a few components manually, I mostly let LLM decide which components to use, how to use them, and letting it decide/generate styling details.

LLM-assisted:

- Name suggestions
- Project setup (linters, formatters, ts compiler settings)
- Checking and Code Review
- Snippet generation
- Explanations of external API details, and confirming browser caching behaviour
