# Bifrost

A fully accessible fediverse client built with PySide6, designed specifically for screen reader users.

## Vibe Coding Project

This project was created through "vibe coding" - a collaborative development approach where a human (Storm Dragon) provides direction, requirements, and testing while an AI assistant (Claude) handles the actual code implementation. Vibe coding combines human creativity and domain expertise with AI's rapid development capabilities, resulting in functional software that meets real accessibility needs.

**All code in this project was written by Claude (Anthropic's AI assistant)** based on specifications and feedback from Storm Dragon.
