Overclock ReworkBrand-new Overclock button — replaced the static fire icon with an animated pixel-art flame. Idle, active, and cooldown each have their own sprite and behaviour CPS heat gradient — when overclocking, the CPS counter in the top bar now smoothly transitions from cyan to red as system stress climbs.Doubled max stress capacity — overclock now takes roughly twice as long to peak, giving you a longer window to ride the production bonus before forced cooldown. -Jabran
