A markdown CMS your AI agent can edit directly. Articles are plain .md on disk — Claude, Cursor, any LLM with file access reads and writes them like a human. No DB on the hot path. No build step. No plugin theatre.
P50 render target (benchmark suite ships v3.1). Markdown parsed once, cached in memory. The hot path never touches a database.

5 renders per wingbeat. The site is faster than the bird.
/ MANIFESTO/ 2026
A site shouldn't take off — it should already be in flight.
Bird is built on the assumption that the next decade of writing is half-human, half-agent, and both should reach for the same plain text. So we cut the weight: no DB on the hot path, no framework, no plugin theatre. Just markdown, on disk, ready in a wingbeat.
