Board notes 5 details

Layout: Move 42 and 0/9 open with superheroes, braided portraits, balloon and headphone children, dreadlocked baseball players, beanie-and-glasses heroes, and costumed rabbits.
Goal: Complete the nine accepted groups, including Curly Haired Superheroes, Braided People in Pink Clothes, Kids with Balloons, Blonde Kids with Headphones, Dreadlocked Baseball Players, Superhero Rabbits, and Superheroes with Glasses & Beanies; the board empties at 9/9.
Opening: Curly Haired Superheroes is the first cleared label; the run then keeps braided pink-clothed portraits separate from balloon children.
Danger Zone: Headphones, braids, beanies, glasses, and costumes overlap across children, athletes, superheroes, and rabbits. The dreadlocked baseball players must stay out of broad hair or hero groups.
Mechanics: The board alternates human and rabbit groups and repeatedly uses two-cue labels such as role plus hairstyle, clothing plus braids, or headwear plus glasses.
