Expand Peggle from 5 to 25 levels (5 per friend) with unique shapes and
progressive difficulty. Each friend block (Ethel, Kona, Zanthor, Fireball,
Victor) gets distinct names, backgrounds, and level layouts.
- Redesign level select: one row per friend showing portrait, name, power,
and their 5 level tiles
- Add friend intro screens: video (or portrait fallback), bio, and power
explainer before each friend's first level
- Intros skip on replay/try-again; input hold prevents accidental cannon
launches after UI clicks
- Add intro videos for Ethel and Kona; document the video system
- Update level generator with `pentagram()` helper and 5 variants per friend
- Verify block integrity, intro markers (1,6,11,16,21), and level name uniqueness
