    // ...]` publishes -- and `pnpm check:published-dist` then reds on a byte-identical
    // tree as soon as anything runs `tsc` (objectui#9189). Pinned in every composite

    // extensionless `./SchemaRenderer` in the emitted dist is unloadable under
    // plain Node (`ERR_MODULE_NOT_FOUND`) — objectui#4538. `tsc` never rewrites
    // specifiers, so what the source writes is what dist ships; the only way to
    // keep the extensions is to have the compiler REJECT a missing one.
    //
    // These two override the root's `"module": "ESNext"` /
    // `"moduleResolution": "bundler"` for THIS package only (the root is shared
    // by 38 packages — flipping it there is a different change). Under
    // `nodenext` a missing extension is TS2835 and a bare directory import is
    // TS2834, so the property is enforced at compile time rather than by
    // review. Emit is unchanged: package.json is `"type": "module"`, so
    // `nodenext` emits the same ESM `ESNext` did.
    //
    // Runtime loadability is pinned separately by `pnpm check:node-esm-load`
    // (scripts/check-node-esm-load.mjs), which actually imports the built entry
    // under plain Node — resolution alone would not have caught this.

  // by hand). Enforced repo-wide by `pnpm check:published-tsconfig-exclude`
