## Summary

Deliver `@suaveplan/react-file-upload` on genesis from scratch at enterprise quality. Drag-and-drop / chunked-upload kit: composite `FileUpload` (Dropzone + FileList + ProgressBar), individual components, `useFileUpload` (chunking, concurrency, progress, cancellation, retry, auto-upload) and `useDropzone` (HTML5 drag-drop + click-to-browse). Pure helpers: `createFileState`, `splitFileIntoChunks`, `validateFile`, `matchesMimePattern`, `createPreviewUrl`, `revokePreviewUrl`, `formatBytes`, `calculateProgress`, `isImageFile`.

## Current-state audit (genesis)

Package does not exist on genesis — fresh build.

## Available workspace deps on genesis

| Package | Role |
|---|---|
| `@suaveplan/error` (`workspace:^`) | `FileUploadError` |
| `@suaveplan/mime` (`workspace:^`) | MIME type validation |
| `@suaveplan/react-translate` (`workspace:^`) | i18n |
| `zod` (`catalog:forms`) | Upload config schemas |
| `@opentelemetry/api` (`catalog:observability`) | `file_upload.complete` span |

## Preserved public API surface

`FileUpload`, `Dropzone`, `FileList`, `ProgressBar`, `useFileUpload`, `useDropzone`, upload-engine helpers + all types.

---

## New additions for genesis

1. **`FileUploadError`** — codes: `FILE_UPLOAD_VALIDATION_FAILED`, `FILE_UPLOAD_CHUNK_FAILED`, `FILE_UPLOAD_NETWORK_ERROR`.
2. **`@suaveplan/mime` integration** — MIME validation via `matchesMimePattern` delegates to `@suaveplan/mime`.
3. **Stories** — every component with default, uploading, complete, error, playground.
4. **Playwright E2E** — file drag-drop, progress bar, cancel upload.
