What Demarkus is

Demarkus implements the Mark Protocol — a minimal protocol for serving versioned markdown over QUIC. It is:

Read-only by default — no writes without explicit auth tokens
Version-preserving — every change is kept, nothing is deleted
Privacy-first — no tracking, no cookies, no user agents logged
Self-hostable — runs on a $30 single-board computer
Graph-aware — persistent document graph with backlink queries across sessions

`demarkus-tui`	Interactive terminal browser with graph view
