Settings & polish
Added four new settings: Abbreviate Numbers (1M instead of 1,000,000), Reduce Motion, Filter Combat Log (hides routine kill spam, keeps level-ups/drops), and Confirm Before Selling.
Confirm Before Selling uses the same "click again to confirm" pulse animation as Sell Everything, not a popup — applies to individual item sells and Sell Commons.
Added press animations to the Enchant panel's Upgrade and Reroll buttons.
Skill tree overhaul
Progressive reveal: you now only see 4 nodes ahead of your current progress on any line, rather than the whole tree stretching into the distance. New nodes fade in as you buy.
A gold burst animation now plays at a node's actual position when you buy it.
Branches now fork off at node 4 instead of 8, and the tree opens fully zoomed in on the hub instead of zoomed out.
Critical purchase bugs fixed
Fire Bomb (and every other spell) was completely unbuyable — the function that actually processes spell purchases had never been written, just referenced.
Every utility line (Chest Capacity, Expedition Tactics, Offline settings, etc.) was also unbuyable for the same reason — that function had gone missing, likely during an earlier cleanup pass.
