### Issue:
Next.js App Router expects params to be a Promise that must be awaited before accessing properties.
### Error:
```
Route "/download/[...segments]" used `params.segments`.
`params` is a Promise and must be unwrapped with `await`
or `React.use()` before accessing its properties.
```
### Solution:
- Made component async: `export default async function DownloadListing`
- Updated params type: `Promise<{ segments: string[] }>`
- Unwrapped with await: `const { segments: rawSegments } = await params`
