/*
 * Shared tab-group (x-global::navigation.tabs) — the ONE tablist skin.
 *
 * Consolidates the four hand-rolled copies of the same visual (board tabs in
 * nav.css, report deck .rd-tabs, goal-dialog .gv-tabs, Resource Allocation
 * .ra-tabs) into a single component stylesheet. Two variants:
 *
 *   .lt-tabs--attached  gradient accent band + translucent framed segment
 *                       group + white active pill (board/report look). Uses
 *                       the theme accents with the conditional --nav-scrim
 *                       (0 for dark accents; raised per-theme where white
 *                       controls would fail WCAG AA on light accents).
 *   .lt-tabs--floating  free-floating fully-rounded glass pills (Resource
 *                       Allocation look); .lt-tabs--dark for dark headers.
 *
 * Behavior (ARIA, keyboard, persistence) lives in the component's script.
