/**
 * css/components/tabs-accordion.css — Website 2.0 shared component
 * library (#125)
 *
 * "The Acquisition Model" pattern — a row of tabs above a click-
 * accordion (one row open at a time within the visible panel; a CSS-
 * border "+"/"−" toggle, not the chevron `accordion.css` uses). `data-
 * open="0|1"` is set by js/theme.js `initCgTabsAccordion()`, which also
 * swaps `.is-active` between `.cg-tabs-panel`s and `aria-selected` on
 * `.cg-tabs__btn`. Reference: services.html `.tabs`/`.accord`/`.arow`/
 * `.ahead`/`.adetail`/`.plus`.
 *
 * Tokens only — no raw hex, no @layer, no !important.
