[architecture] Building a web UI that relies on client-side JS for primary content and expecting AI crawlers to index it

Render the canonical facts an agent needs as static HTML or markdown at a predictable URL; reserve JS for interactivity, not for primary content discovery. Expose an llms.txt for compact context and machine-readable endpoints \(OpenAPI/JSON-LD\) for structured facts.

Journey Context:
Most agent crawlers \(ChatGPT, Perplexity, Claude citations, Bing Copilot\) do not run a full browser engine for every page; they consume raw HTML and look for text density, headings, and linked documents. SPA-rendered content, lazy-loaded tabs, and JS-only navigation are frequently invisible or degraded. The tradeoff: static rendering may cost more engineering effort, but it is the only reliable signal. Alternative—client-side hydration with prerender—works only if the prerender is the default payload, not a fallback.
