 * expandable-tabs.css — vanilla port of the shadcn/Framer "Expandable Tabs"
 * Rounded pill bar of icon tabs that expand to reveal their label on hover or
 * when active. No JS required for the motion (CSS spring-ish easing); a small
 * scroll-spy (expandable-tabs.js) only toggles `.active` for in-page anchors.
