Block Colors - new acquisition system
Previously all sand colors were just unlocked from the start. Now:
You begin with 4 base colors per palette (free).
3 additional color slots can be purchased with coins (up to 7 colors total per palette).
More active colors = harder to read the board, but you get a score bonus for it: each color above the base 4 adds +8% score. Running the full 7 colors gives you a solid +24% bonus.
You can toggle which unlocked colors are active at any time - as long as at least 4 stay active.

Daily Challenge - leaderboard fix
Fixed a bug where the Daily Challenge score wasn't resetting properly. If you set a good score and then didn't play for a while (even a full week), you could stay locked in at #1 on the leaderboard the entire time, since your old score never expired or got replaced. Daily Challenge standings now refresh correctly, so the board reflects actual recent play instead of a stale score from days ago.

Floating score popup - a "+250" (etc.) number now pops up over the board whenever you clear a line, so you don't have to keep glancing up at the score counter.
Block clear animation - cleared blocks now fade out instead of vanishing instantly, and the animation matches your equipped Clear Effect skin (Sparkle, Confetti, Embers, or the classic white flash for None).

Reworked the default piece colors using a colorblind-safe palette, so all 7 piece types are easy to tell apart at a glance.
Fine-tuned two colors on the default theme that were still a bit too close to each other.

Fixed poor contrast between block colors that made pieces hard to distinguish, especially on the default (Wood) theme.
