UI improvements + minor bug fixes

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.
