 **Restrictions hint** — both components auto-render an "allowed types / max size" hint below the field. Hide it with `showRestrictions={false}` when the same info lives elsewhere (e.g. a `tooltip`); rejection error messages still render either way:
 ```tsx
-<FileDropzone label="Drop files" accept=".pdf,.txt" maxSize={5} tooltip="PDF/TXT, max 5 MB" showRestrictions={false} />
+<FileDropzone label="Drop files" accept=".pdf,.txt" maxSize={5 * 1024 ** 2} tooltip="PDF/TXT, max 5 MB" showRestrictions={false} />
 ```
 
 **Rejections are reported and observable** — a file failing `accept`/`maxSize` (dragged *or* picked) surfaces a localised message, and `onChange` fires even when the drop is fully rejected (with the unchanged list), so single-file rejections aren't silent.
