/* Dark-only palette, deliberately in the same family as llamanexus.makershop.fi's
   style.css (same neutral scale: --bg/--bg-elevated/--border/--text/--text-muted,
   same .site-header/.hero/.product-grid/.site-footer building blocks) so the two
   sites read as part of the same maker's work, with FastECU's own warm
   red-orange accent standing in for LlamaNexus's terracotta one. Everything
   below the neutral tokens is plain hand-written CSS, no build step, no
   framework — just static files a PHP host can serve as-is. */
