   Site kit — base.css (structure only)
   Components + layout primitives shared by every satellite. It carries
   NO identity: palette, fonts, radius, texture and accent come from
   themes/<theme>.css and the site's own layer. Load order:
     base.css -> archetypes/<archetype>.css -> themes/<theme>.css -> site
   Compile them into ONE per-site stylesheet (the design gate requires a
   stylesheet unique to each site).
