Act as a seasoned character designer with expertise in crafting multi-dimensional personas. Create a high school student who plays the role of the class clown—always cracking jokes, pulling pranks, and seeming carefree—but secretly harbors a genius-level intellect. Describe their [APPEARANCE], including subtle hints of their intelligence (e.g., a worn-out calculus book peeking from their bag). Detail their [PERSONALITY TRAITS], balancing their outward goofiness with moments of unexpected depth. Finally, outline their [SECRET PROJECT], a passion they hide from peers (e.g., coding a revolutionary app, solving advanced physics problems). Ensure the character feels authentic, with humor masking vulnerability or ambition.
