Single‑file site search redirect page. Map a short query keyword to a target site using regex patterns and redirect immediately. Meant to be used in a Chrome custom search engine (keyword -> URL?q=%s).

• Single HTML file with inlined JS and CSS for minimal latency
• Pattern list: array of { pattern, url } (JS regex + URL template with $1)
• Immediately redirects to the first matching pattern when ?q= is present
• Shows a simple table of patterns when no query is provided
• No dependencies, no build step

1. Configure Chrome custom search engine:
   • Search engine: Quick Search
   • Keyword: q
   • URL: file:///path/to/index.html?q=%s (or https://your-host/index.html?q=%s)
2. From the address bar use: q gh typescript → redirects to GitHub search for "typescript".

• Add new entries to the PATTERNS array in the file: each entry must include a capturing group and a $1 placeholder in the url template.
