The code behind this page

This is exactly what this page sends to Google, Bing, ChatGPT, Claude, Perplexity and Gemini. We publish it in the open for two reasons: so you can see nothing here is hidden or made up, and so any business or developer can copy it. Being a good local AI steward means the machine version says exactly what the human version says.

1. HTTP response headers

Sent before the page. They tell crawlers the canonical address and that a plain markdown copy exists.

2. Head tags

Title, description, canonical, robots and Open Graph tags. This is what shows in search results and link previews.

This is the evidence for every fact on this page, across Locals, Services, Team, Visit, Reputation and Updates. Each reference names the fact, the source, what kind of source it is, and the date it was checked, with a link and an archived copy so anyone can verify it. Visitor references are dated firsthand accounts. AI guesses record what an AI engine said on that date, not what is true.
