The **san-html-cases** repository is a collection of reference HTML outputs, components, and test specifications that define how the **San** front‑end framework and its server‑side rendering counterpart **san‑ssr** should generate and hydrate markup in various usage scenarios. It is used by the San core, san‑ssr, and the PHP‑targeted SSR projects to drive their end‑to‑end tests and ensure compliance with the HTML specification. This repo is aimed at developers and contributors of the San ecosystem who need reliable test cases and a canonical HTML spec for San components.
