/* Newzino Connections daily game styles.
 *
 * Layout is mostly Tailwind classes inline in the templates. This file holds:
 *   - 4x4 tile grid with consistent square ratios
 *   - Selection state (rose accent ring + lift)
 *   - Shake animation for "one away" and "wrong" feedback
 *   - Solved-group pill animation (4 tiles consolidate into a single colored bar)
 *   - Tier-color tokens used in both the live game and the share grid
