[1.7.4] Polish Prestige Page && Minor Improvements

Prestige Page

• Auto-center on the first available upgrade now actually works

• Updated misleading copy in the prestige tutorials

• SVG connector lines no longer trigger per-frame getBoundingClientRect reflows — they stay glued to the cards during pan/zoom without lag

• Removed Quick Start I/II/III and the Momentum 1/2/3 chain from the prestige tree

General

• Fixed first-launch language detection — the game now respects your Steam UI / OS language on first run

• Tuned several generators across the whole game

Cube Garden

• Brewing a crop into a potion now grants mastery progress (previously only selling did)

• New per-plant Growth Mastery multiplier — cumulative sales reduce that plant's grow time by up to 30%

• The seed picker menu now shows the mastery-adjusted grow time
