// We can't use a RegExp:
//  - Needs to work with Micromatch: https://github.com/micromatch/micromatch because:
//    - Vite's `import.meta.glob()` uses Micromatch
//  - We need this to be a allowlist because:
//   - A pattern `*([a-zA-Z0-9]` doesn't work.
//     - Because of ReScript: `.res` are ReScript source files which need to be ignored. (The ReScript compiler generates `.js` files alongside `.res` files.)
//   - Block listing doesn't work.
//     - We cannot implement a blocklist with a glob pattern.
//     - A post `import.meta.glob()` blocklist filtering doesn't work because Vite would still process the files (e.g. including them in the bundle).
