Opportunity BasketHackerNews Theme Proxy Service
A lightweight proxy server that sits between users and Hacker News, intercepting HTML responses and injecting custom CSS/dark mode styling in real-time without requiring browser extensions or third-party apps. Users configure their preferences once (dark mode, font size, layout tweaks) and access HN through a custom domain (e.g., hn-dark.proxy.com) that transparently applies their settings.

The platform refuses to implement native support despite 6+ years of requests, leaving power users running elaborate workarounds that break frequently and create worse user experiences than the original problem.
