Any additional comments?

vite-env.d.ts

interface ImportMetaEnv {
  readonly VITE_XX: number
  readonly VITE_OO: string
  readonly VITE_XXOO: boolean
}

interface ImportMeta {
  readonly env: ImportMetaEnv
}

1. This is about Vite, not Vue
2. all env variables from .env files are always strings at runtime. Telling typescript otherwise won't change what happens at runtime.
