/**
 * Insights tab — Chart carousel styles (v6-mini-app-s3)
 *
 * Key patterns:
 *  - .insights-period-bar: period selector row (Today / 7d / 30d)
 *  - .chart-carousel: full-width scroll-snap container
 *  - .chart-slide: one chart per slide, 100% width
 *  - .chart-dots: indicator row
 *  - .chart-skeleton: placeholder during load
 *
 * Removed in v6-mini-app-s3:
 *  - .chart-filter-overlay (date filter overlay — replaced by period selector)
