Art Skill

Complete visual content system using the PAI Visual Aesthetic.

Core Aesthetic

Tron-meets-Excalidraw - Digital warmth combining:

Hand-drawn Excalidraw-style sketch lines (NOT clean vectors)
Dark slate backgrounds for modern contrast
Neon orange (warmth) + cyan (tech) accents
Subtle glows on key elements
