/* BASE - reset + brand body font, guaranteed on every page that loads the
   shared chrome. Mount-pattern pages also ship this in their page stylesheet
   (identical rules, so this is a no-op for them); native-port pages that load
   only shared.css + tokens depend on it. Without it, components authored for
   border-box + zeroed margins render with browser defaults: padding overflows
   card widths and body copy falls back to the default serif. */
