"""diet_guard: log what you eat, see the daily number, gate the desktop.

The package has three layers, built in order:

* the tracker (this milestone): a low-friction CLI that estimates the
  calories of a free-text meal and appends a tamper-evident entry to a
  per-day log;
* the gate (next): a screen-lock that will not dismiss until a recent meal
  is logged -- the "log-to-unlock" enforcement;
* the escalation (later): a daily report that tightens the other personal
  enforcers (games, PC uptime) when logging is skipped or the budget blown.
