/* dash-tabs.css — VERBATIM port of legacy panel selector + global search.
   Sources:
     legacy dashboard-layout.css :67-95    (.dash-tabs / .dash-tab)
     legacy components-misc.css  :310-328  (.dash-tab extras + tab-panel anim)
     legacy responsive.css       :1-126    (mobile dash-tabs + dropdown)
     legacy dashboard-widgets.css :3-70    (.dash-search + results dropdown)
   Variables (--white, --gray-100, --text-light, --primary, --primary-light,
   --bg-hover, --warning-bg) are aliased in tokens.css to the new tokens,
   so the legacy property values are reproduced exactly without rewrites. */
