FileUpload: expose native attributes for FilePond drop label / drop panel

[mikulabc]

I ran into a small FileUpload UX case where I wanted the FilePond drop zone to show a pointer cursor on hover, since the drop zone is clickable.

FileUpload::extraAttributes() applies to the outer Filament wrapper, and extraInputAttributes() applies to the hidden/native file input, but neither reaches the FilePond-generated drop label or panel.

Right now the only practical app-side solution seems to be scoped theme CSS like:

.my-upload .filepond--drop-label,
.my-upload .filepond--drop-label label,
.my-upload .filepond--panel-root {
    cursor: pointer;
}

That works, but it targets FilePond internals from application CSS.

Would you be open to a native API for this, for example something like:

FileUpload::make('csv')
    ->dropLabelAttributes(['class' => 'cursor-pointer']);

or perhaps a broader API such as:

FileUpload::make('csv')
    ->filePondPanelAttributes(['class' => 'cursor-pointer']);

The goal would be to avoid custom CSS selectors for simple interaction styling on the generated FilePond drop area.
