UI/UX Pro Max Search - BM25 search engine for UI/UX style guides
Usage: python search.py "<query>" [--domain <domain>] [--stack <stack>] [--max-results 3]
       python search.py "<query>" --design-system [-p "Project Name"]
       python search.py "<query>" --design-system --persist [-p "Project Name"] [--page "dashboard"]

Domains: style, prompt, color, chart, landing, product, ux, typography
Stacks: html-tailwind, react, nextjs

Persistence (Master + Overrides pattern):
  --persist    Save design system to design-system/MASTER.md
  --page       Also create a page-specific override file in design-system/pages/
