+`TileMapData` (`{ id, x, y, dx?, dy? }` — тайл + смещение от центра ромба в px);

+const s = map.addDecor(x, y, texture, { dx: 2, dy: -1 }); // рантайм, один спрайт на тайл
+map.clearDecor(x, y);                                     // убрать
+```
+
+- `setTile` декор не трогает (посадка цветов не стирает кустики).
+- Повторный `addDecor` на тот же тайл заменяет предыдущий спрайт.
+- В файле карты — `MapFileV1.decor` (опционально), `parseMap` валидирует
+  границы и целые координаты.
