   Prototype base layer — reset + primitives on top of tokens.css
   Import order:  tokens.css  ->  base.css  ->  prototype styles
   Shared by the gateway (login/portal) and every prototype that
   opts in. Keep it minimal: a normalize, sane defaults, nothing
   opinionated enough to fight a prototype's own look.
