/*
 * OHE Admin Dashboard v2 — Shell CSS
 *
 * Topbar + sidebar + main content scaffold. Ported from atelier-os mock.
 * Loaded after tokens.css (vars + fonts) and before style.css.
 *
 * Class names are namespaced (`tb-`, `app-`, `nav-`) so they don't collide
 * with the legacy style.css selectors. Phase 1 (DASHBOARD-005b) will fold
 * component styles into one file.
