Generate a 5-second 2D anime-style video clip, hand-drawn cel animation like classic 90s anime (e.g., Sailor Moon vibe), 1080p resolution, smooth 24fps with subtle line art and flat shading, no 3D effects. Feature the StarAI mascot: a cute teenage anime girl with long wavy purple hair flowing in the wind, large expressive emerald green eyes sparkling with curiosity, fair skin, wearing a sleek black jacket with neon star patches, short pleated skirt, and knee-high boots. She stands on a glowing rooftop in a starry cyberpunk city at night, holding a holographic star orb that pulses with blue energy. She smiles confidently, tosses the orb upward where it explodes into twinkling stars raining down like fireworks, her hair and skirt billowing gently. Camera starts with a medium shot on her face, then pans up to follow the orb's arc, ending on her silhouetted pose against a vibrant purple skyline dotted with floating AI drones. Soft glowing outlines, minimal particle effects for stars, upbeat chiptune soundtrack with synth waves, no dialogue, whimsical and empowering atmosphere.
