 ## Game Overview
 
 `tarinai_` is an observation sandbox about small creatures called tarinai. The player places food, furniture, hazards, machines, and environment tools, then watches how individuals live, move, eat, sleep, panic, fight, reproduce, get sick, recover, and leave family records.

 - Mutable runtime lives on `window`; primary entities are `World`, `Tarinai`, items, structures, ants, family graph, weather, and save snapshots.
 - Update loop: `main.js` creates the world/UI loop; `World.update` delegates to `TarinaiSystemOrder.update`; `system_order.js` runs named phases.
 - UI loop: pointer/tool/UI intents go through `command_dispatcher.js`; canvas drawing is in render modules; side panels are `ui_*.js`.
