I think a single oxfmt run in the root of a monorepo should be enough to correctly and consistently format every file using its nearest config file.

If there's a discussion about nested configs and only nested configs, I'm sorry but I couldn't find it!

With this directory structure:

├── package-1/
│   ├── lib/
│   │   └── file-1.tsx
│   ├── package.json
├── package-2/
│   ├── lib/
│   │   └── file-2.tsx
│   ├── .oxfmtrc.json
│   ├── .prettierrc.json
│   ├── package.json
│   └── tailwind.css
├── .oxfmtrc.json
├── .prettierrc.json
└── package.json

Unfortunately Oxfmt is broken compared to Prettier:

• ✅ prettier walks from each source file to its nearest config file
• ⚠️ oxfmt uses the config file in the current working directory only

This makes it very hard to migrate to Oxfmt if you're using multiple Prettier configs and/or prettier-plugin-tailwindcss, because now you need to orchestrate per-package oxfmt runs, avoid their results colliding, do very weird things to configure the IDE, etc. etc.
