 * Shared component library for every country dashboard. Depends on
 * theme/tokens.css (load tokens.css first). All colours reference semantic
 * tokens — there are no hardcoded hex values, so light/dark and re-theming
 * "just work".
 *
 * Sections:
 *   1. Reset & base
 *   2. Header + brand lockup
 *   3. Navigation (section-nav tabs + app-nav bar)
 *   4. Layout (main / wrap / panel / grids)
 *   5. Controls (select / tabs / toggle / buttons)
 *   6. Vote-flow: sankey, transition matrix, backtest
 *   7. Charts: legend, local-trend axes
 *   8. Polls tracker
 *   9. KNN lookup
 *  10. Cartes / area explorer
 *  11. Analysis modules: scenario cards, seat table, hemicycle, majority meter
 *  12. Status: live-badge, disclaimer, render-error, tooltips
