-# Chick Sorter v11.0 Routing / Compact Upgrades
-
-Open `index.html` in a browser.
-
-## v11.0 changes
-
-- Egg Farm price is now JPY 300.
-- Initial S2-to-Truck conveyor lane is longer.
-- Egg Farm shutters reopen in Build phase after each day.
-- Mixer and Truck upgrades have no level cap. Each upgrade increases income and matching fines by `ceil(base × 1.05^upgrade count)`.
-- Manual Scanner and Conveyor upgrade choices are removed.
-- Equipment click menu is a compact bubble instead of a large overlay.
-- Explosion damage is `ceil(equipment price / 30)`.
-- Spawn blocking now highlights the stopped chick instead of showing `WAIT`.
-- Scanner/facility routing is more tolerant after manual conveyor dragging.
-
-## 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
