   RS Milow Audio -- shared design tokens + primitives used across every
   page (main site, account pages). Single, deliberately dark visual
   world (a lit rack of analog-style hardware in a dim studio), so this
   stays one committed theme rather than trying to invert into a
   "light mode vintage rack", which isn't a coherent thing. Background
   and every color are painted explicitly regardless of host theme.
