Fast commit graph
git2 reads + a hand-tuned Rust swimlane layout on a virtualized canvas — scrolls smoothly with readable text even on a 150k-commit repo, and checkout updates instantly instead of reloading.
Every operation that touches your history is reversible — Tama pins a snapshot before every mutation, so a global Undo is always one keystroke away.

A real session on CPython — scroll the graph, inspect a signed commit, fuzzy-search with ⌘K, and rewind with ⌘Z, every mutation snapshot-backed.
