Show HN: Keyboard-first Hacker News client with a twist

I built this because I noticed that when I use Hacker News, I mostly read the comments, however large threads can be hard to skim, especially when useful information is buried several levels deep.

This is a proof-of-concept HN reader focused on comment-heavy threads. It has keyboard-first navigation on desktop, makes large discussions easier to scan, and shows at a glance whether the submitted link has appeared on HN before.

It should work on mobile, but desktop is the main target for now. The app is still young and rough around the edges, so I’d appreciate feedback on the reading flow, keyboard navigation, etc.
