Claude's download page only detects your OS on a direct visit

I found a small but visible UI bug on Claude's download page, claude.ai/download.

What happens

• Direct visit: the page detects your operating system and shows the matching download options.
• Arriving from another page (for example claude.ai/downloads, then "Download for Linux"): the OS check doesn't run. Every platform's button is shown, and the "Windows (arm64)" and "macOS" buttons render on top of each other.

Steps to reproduce

1. Open claude.ai/downloads
2. Click "Download for Linux"
3. Look at the download buttons on claude.ai/download

Seen in Chrome on Fedora Linux.

Likely cause

My guess: the OS detection only runs on a full page load, so an in-app navigation renders the fallback "all platforms" layout, and that layout was never checked with all five buttons visible at once.
