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.
