 * Toggle without touching the default look — the same components re-render in the
 * Microsoft Fluent / Power BI visual idiom: Segoe UI, Power BI blue accent, flat
 * surfaces, tight corners. Load AFTER librevolve.theme.css so it wins when active.
 *
 * Scope of this first cut: the chrome (header, cards, buttons, pills, accent,
 * type). The chart palettes (heatmap / leverage graph / plots) are set in JS and
 * are themed in a following pass; see librevolve.powerbi.charts (planned).
