What ships with every build
This is a specification rather than a philosophy, so it is worth writing as one. One indexable URL for every thing worth finding — every property, every episode, every program, every service somebody might search for on its own. Exactly one heading that says what the page is. A title and a description written for that page rather than inherited from the last one. A canonical address. A share image. Structured data describing what is actually visible. A sitemap whose dates mean something. A robots file that names the AI crawlers explicitly rather than leaving it to inference. And a machine-readable summary at llms.txt.
None of that is exotic and none of it is expensive at build time. All of it is expensive to retrofit, which is the entire argument for doing it while the site is being made rather than as a project the following year.
