📦 Radiant Smile

Radiant Smile, Full radiant grin, eyes crinkled into joyful crescents, cheeks flushed with warmth. Full muscle activation: a true Duchenne activation — zygomaticus major pulls the mouth corners up and outward while orbicularis oculi contracts to raise the cheeks and crease crow's feet at the outer eye corners (both must fire, or the smile reads as fake).
