   Coassisted static-site default theme.
   Vanilla CSS, no framework. Override per-site by creating
   <node>/static-site/theme.css — that file is concatenated AFTER
   this one, so overrides win. CSS variables on :root make most
   tweaks one-line jobs.

   Design language: dark-first, gentle glows, subtle grid,
   restrained typography. Lifted-but-simplified from
   ~/Documents/dev/sites/weldpad-static/styles.css.
