- All 16 icons redrawn as rich multi-color SVGs (houses, towers,
factory, plants with smoke, services with badges/crosses, park,
fountain, stadium) — unique gradient ids, no collisions
- Toolbar grouped under labeled sections: Tools / Zones / Power /
Safety / Health / Leisure
- Every button shows price (FREE for zones); unaffordable buildings
dim and turn red as funds change
- Keyboard-shortcut badges on buttons; bigger 30px icons; hover lift
- Floating status chip above the bar shows active tool, price,
upkeep and coverage radius (SimCity status-bar feel)
- FIX: Game.ui was a method while input.js read it as a property, so
tool-change UI updates silently never ran; now a proper getter
