Major
Shop shows prices (better). Every card and relic now has a price chip. Affordable items render in gold, unaffordable items grey out. Hover shows what you can afford.
"Boss in N" actually means something. The countdown now points to the real act bosses (floors 8, 16, 24), not the every-three-floor segment markers that made it useless on floor 1.
Combat HUD decluttered. During fights, the top bar shows only your floor. No more act name and boss countdown competing for attention.
Hand fan looks like a hand fan again. Chain-matched cards no longer punch forward and ruin the curve. They lift a little, the rest of the fan stays uniform.
Selected card and CHARGE button no longer overlap. Cards lift a sensible amount and the CHARGE button stays anchored above the card top.
Run-end screens no longer show impossible numbers. Defeat bars stay within their bounds. Victory encounter count matches your actual wins.
Minor
HP bar sits properly centered in the top bar and no longer jumps when statuses are applied.
Status effect chips now live in a row directly below the HP bar instead of squeezing the HP bar or floating in a phantom slot at the bottom of the screen.
Brain Fog and Flow State render as proper chips alongside everything else.
Chain glow on cards is now a tight pixel-art outline instead of a fuzzy purple cloud, and all chain-matched cards breathe in sync.
Removed the redundant "AP" label under the action point orb.
Multi-hit debuff intents no longer duplicate the same line in their hover tooltip.
Enemy sprite repositions immediately when the quiz opens or closes, instead of waiting for its current animation.
Map node-type legend is always visible at the bottom, and path strokes are thicker.
Status chip popups stay on-screen instead of clipping off the left edge near the HP bar.
The pre-run chain-color distribution screen now hides the in-run HUD so the colors are the only thing on screen.
