In-depth analysis
AI search engines prefer structured Q&A (FAQPage) and a clear content hierarchy; plain prose rarely gets cited as the answer. Architecture should be edge-first — static pre-render sinks to the edge, dynamic capability falls back to functions with circuit breakers.

Why is my Astro component's interactivity not working?
Components ship as zero-JS HTML by default, so an interactive one needs a client:* directive (client:load, client:visible, …). Without it the script is never bundled into the page.
