Summary

This PR scopes a CSS rule to the Home upload panel and constrains the upload list height so action controls remain visible with long file lists. The change is small, targeted, and aligns with the stated intent of avoiding side effects in other views. I don’t see blocking issues; it looks ready to merge.

Praise

• src/renderer/components/UploadPanel.tsx:489 — Scoped wrapper for localized styling: Wrapping the panel in home-upload-panel is a clean way to avoid globally affecting Ant upload lists elsewhere.
• src/renderer/App.css:50 — Practical overflow control: Applying max-height + overflow-y: auto on .ant-upload-list directly addresses the overlap issue while preserving access to all files via scrolling.
• src/renderer/App.css:53 — Scrollbar stability improvement: Using scrollbar-gutter: stable helps reduce layout shift when the scrollbar appears, improving UI consistency.
