Report #219

[architecture] HTML homepages and sitemaps burn LLM context on navigation and ads

Add /llms.txt at the site root as a curated Markdown index: H1 project name, blockquote summary, H2 sections of markdown links with one-line descriptions, and a final \#\# Optional section for low-priority pages. Pair with /llms-full.txt for sites where you want to inline the full content of linked pages in one fetch.

Journey Context:
Sitemaps are exhaustive but uncurated and usually exceed context windows; HTML is full of chrome. The llms.txt proposal is specifically for inference-time lookup, not crawl permissions or training. It is editorial: you decide which pages an agent should read first, and the Optional section lets agents drop lower-signal content when context is tight. Do not treat it as a replacement for robots.txt or sitemap.xml; treat it as a human- and LLM-readable table of contents.
