// Gentelella v4 — TypeScript declarations for the public JS surface.
//
// Drop this file at `types/gentelella.d.ts` and add `"types": "types/gentelella.d.ts"`
// to `package.json` (already done). VS Code then resolves type info for every
// `import { ... } from 'src/v4/...'` automatically — no tsconfig needed,
// no .ts files required, IntelliSense + parameter hints just work.
//
// If you DO use TypeScript, you can also `import type { ModalAction } from
// 'gentelella'` etc. — the named exports below are reachable via the
// per-module declarations.
