+
+Open `index.html` in a browser.
+
+## v10.7 changes
+
+- Reduced excessive rule/help text. Only essential routing/status is shown.
+- Moved the build grid lower so the top rows are not hidden by HUD/status UI.
+- Added egg farm shutter animation when the timer reaches 0. Farms stop producing; the remaining chicks must clear before Build phase.
+- Facility bodies cannot overlap when building or dragging.
+- Mixer / Shredder / Truck receiver ports remain on the grid edge while bodies sit outside the grid.
+- Output route arrows are color-coded:
+  - Mixer: blue
+  - Shredder: green
+  - Truck: pink
+  - If one belt segment carries multiple destination routes, multiple colored guide lines are drawn. Duplicate same-destination lines are collapsed.
+- Next Turn is blocked unless Mixer, Shredder, and Truck receiver ports are connected to conveyor.
+- Truck visual cargo is cleared before Build phase so females do not remain displayed in the truck after settlement.
+
+## Controls
+
+Sorting:
+- S1: A = Mixer, D = S2
+- S2: Left Arrow = Shredder, Right Arrow = Truck
+
+Build phase:
+- Left drag empty area: box select
+- Drag selected equipment: move selection
+- Right drag: pan
+- Ctrl+Z / Ctrl+Y: undo / redo
