◆ WHY DOTBOX
━━━━━━━━━━━━━━━━━━━━━━━━
◉ Polished visuals. Hand-crafted typography, neon-on-dark theme, and smooth Skia-rendered animations. No stock assets, no generic clip-art.

◉ Cosmetic customization. Earn stars, unlock dot shapes, line styles, and box effects. Five categories, dozens of combinations.
◉ Works offline. vs AI, Levels, Pass & Play, and Endless modes require zero internet. Online multiplayer needs a connection, of course.
◉ Respect for your time. No ads mid-match. No pay-to-win. No energy meters. No daily login shame. Just play.
◉ Crash-recovery built in. Lose signal mid-move? The game saves after every line. Open the app, resume right where you left off.

◆ HOW TO PLAY (30-SECOND PRIMER)
━━━━━━━━━━━━━━━━━━━━━━━━
1. Take turns drawing one line between two adjacent dots.
2. When you close the fourth side of a square, you claim it and get another turn.
3. When all lines are drawn, whoever captured the most squares wins.
Sounds simple. It isn't. The game is a microcosm of sacrifice, parity, and chain control — a genuine strategy puzzle disguised as a children's game.
