Adds two primary modes on top of the original LLM-generation approach:
- Mode 1: pyfiglet (571 fonts, pip install, no API key) for text banners
- Mode 2: asciiart.eu search (11,000+ pieces) via web_extract for pre-made art
- Mode 3: LLM-generated art using Unicode palette (original PR, now fallback)
Includes decision flow, font recommendations, and category reference.
Unicode-based ASCII art generator skill with multiple styles
(block, shadow, outlined, gradient, decorative frame), character
palette reference, and usage examples. No external dependencies.
