Upgrade trees, re-laid out. Bigger, more legible nodes. Prices now show on the node itself instead of only on hover, and glyph colours group upgrades by effect family — damage, reach, tempo, control, sustain. The base tree keeps its branch headers pinned while you scroll and marks every fifth row, so 90 nodes are finally navigable.
Tower stats on hover. Hovering a build button now shows damage, fire rate, DPS, range and targeting class — with your unlocked upgrades already applied, so you see the tower you would actually place. Multi-target turrets show their volley count, beacons their aura bonus.
Rebuilt top bar. Run state is grouped together instead of scattered among the buttons. HP and shield have meters that shift to amber and red as they drop. The buttons that end a run no longer look identical to the harmless ones.
Exit button in the main menu.
No balance changes — no tower, cost or upgrade was touched.
