Generate marketing demo HTML for any repository using a hook+demo pipeline. This skill scans source code into <code="..."> blocks, creates plan outlines, generates hook/demo HTML, and optionally merges them. Use when you need one-click demo generation for arbitrary repos with Gemini CLI (`gemini -m`), including selectable hook templates (`text`, `shorts`, `4methods`).

Repo Demo Generator

Generate demo assets from any codebase in 3 stages:
  1. Extract code context as 
    <code="path">...
    blocks
  2. Generate outlines (hook outline + demo outline)
  3. Generate HTML (hook, demo, and merged)
