    // which reads `context.getFilename()` - removed in v10. Naming a version
    // skips the branch outright, so the plugin's rules keep working; nothing
    // here disables them. Read from React's own manifest rather than typed as a
    // literal, because a hardcoded "19" is a figure that goes stale silently the
    // next time React majors and nothing would fail to tell us.

    // it parses with `eslint-config-next/parser`, a re-export of Next's compiled
    // `@babel/eslint-parser`, whose `ScopeManager` predates v10's `addGlobals` -
    // and the preset declares over a thousand globals, so v10 calls it on every
    // such file and throws. Routing them through the TypeScript parser avoids it.
    // `.mts` and `.cts` are in this list because they are not: they are
    // TypeScript, but the preset's TS block does not claim them, so they reached
    // the Babel parser and were the last two files still failing.
    // The cost is that `next/babel`-specific syntax would no longer parse in a
    // plain `.js` file. Nothing here is such a file - these are config and
    // `scripts/*.mjs` - so it costs nothing today, and would announce itself
    // loudly rather than silently if that changed.
