- Replace drawn ball textures with 32-frame rolling cycle + fixed specular
highlight, so marbles visibly rotate as they travel along the path
- Switch from Phaser Containers to a Layer for proper depth-sorted rendering
- Replace hand-drawn frog with assets/images/zuma/frog.png sprite sheet
(2 frames: base disc + slotted overlay for the mouth)
- Add ZumaEditor (/?zuma-editor=1): drag/insert/delete path points, move
frog, tune parameters, test-play, export bank or single level
- Increase BALL_RADIUS 24→32, BALL_SPACING 48→64, and rebalance all tuning
constants (catchup/pullback speeds, explosion radius, frog clearance)
- Extract geometry lint (validateLevel, validateLevelParams) into ZumaLogic
so genZuma.js, verifyZuma.js, and the editor share identical rules
- Rewrite genZuma.js with a Pen class (straights + circular arcs at uniform
STEP=70px) to avoid Catmull-Rom overshoot; regenerate all 20 levels
- Update verifyZuma.js aimbot soak: 8 seeds/level, ≥80% bank clear rate,
star curve calibrated above mechanical play
- Update level data: new coordinates, adjusted quotas/speeds/colors/scores
- Add new background images (background-01.png, background-02.png)
