/* @weproject/browse-kit — toolbar styles.
   Every colour resolves through a fallback chain so the same sheet renders on
   three vocabularies — Data Domain's console (--accent, --txt, --mut, --line,
   --panel, --panel2: the set chart-kit's analysisPivot.css resolves first),
   Supremacy's (--tx-N, --bg-N, --br-N, --lt-core) and Academy's design-kit
   --ds-NAME-rgb triplets — and, with none of them, a neutral default. Hairlines,
   no shadows; the row wraps at phone width. (No asterisk-slash pairs in this
   comment: "--tx-*" followed by "/" once closed it three lines early.) */
