spec/tests/test-render-html.sx covers the full HTML serialization surface:
text/literals, content escaping, attribute escaping, normal elements,
all 14 void elements, 18 boolean attributes, regular/data-*/aria-* attrs,
fragments, raw HTML, headings, lists, tables, forms, media, semantic
elements, SVG, control flow (if/when/cond), let bindings, map/for-each,
components (simple/children/keyword+children/nested), macros, begin/do,
letrec, scope/provide, islands with hydration markers, lakes, marshes,
threading, define-in-template.
Validates adapter-html.sx can replace sx_render.ml as the canonical renderer.
