Chick Sorter v14.0 Zunda Tax / Resale

Changes in this build

• Changed Egg Farm build price to ￥250.
• Replaced the previous daily Fairies fee with ZUNDA TAX, paid when Next Day is pressed.
• ZUNDA TAX taxes only cash above ￥500: ceil((cash - 500) × rate), with 5% added per ￥500 band and a 95% cap.
• Removing equipment from a previous Build phase now sells it for 50% of its build price; same-Build removals still refund 100%.
• Removed visible STOPPED text/highlight. Blocked chicks simply stay still.
• Removed route-overlay arrows/colored flow arrows. Conveyor movement is now shown by small direction triangles inside belt tiles.
• Moved the starter S1 position lower so the Egg Farm and S1 have more distance.
• Moved the Truck to the bottom side of the grid and connected the starter S2-to-Truck belt to the new receiver.
• Made scanner and facility ports strict: a belt must occupy the exact port cell to count as connected.
• Expanded Next Day validation to scanner inputs/outputs and planned output routes, not just machine receiver cells.
• Build buttons for unaffordable equipment, or already-built unique machines, are disabled and visually faded.
• Removed Close buttons from clicked-equipment/upgrade popovers. Click outside the popover to close it.
• Kept src/index.html and src/styles.css removed; the project uses the root index.html and styles.css only.
• Continued centralized price/income/fine/facility definitions in src/core/config.js, shared text in src/core/text.js, and economy logic in src/systems/economy.js.

Structure ideas for the next cleanup pass

• Move HTML button content to a data-rendered build panel instead of hard-coded markup.
• Give every equipment object a defId, so runtime state never duplicates names, prices, sizes, or upgrade rules.
• Store routes as cell arrays and convert to pixel paths only at movement/draw time.
• Cache route plans per build session, then invalidate once on build/erase/drag instead of recomputing every draw.
• Split route validation into errors and warnings, so optional/unused equipment can be supported later without blocking the day.
• Remove legacy fallback paths after save compatibility is no longer needed.
