Some checks failed
Check / eval (push) Has been cancelled
The machine flake's git-tracked settings file is system state, not "theme" only — rename it to state.json. CLI becomes nomarchy-state-sync with a nomarchy-theme-sync symlink for scripts and muscle memory. Eval (mkFlake, doctor, lifecycle) still accepts theme-state.json; the next write migrates to state.json and removes the legacy file. Documented in MIGRATION.md; drop the CLI alias after release notes.

# Automatic timezone detection (opt-in) — the system timezone, and so the
