/**
 * watchlist-strip.css — Multi-Ticker Watchlist Selection Panel Styling
 *
 * Styles the WatchlistStrip panel's horizontal card layout, broker badges,
 * position state pills, sparklines, animations, and interactive states.
 * Loaded as external <link> from unified-dashboard.html for design ownership
 * and reusability. Fallback minimal CSS injected by JS as safety net.
 *
 * All class names prefixed `ws-` (WatchlistStrip namespace) to prevent
 * collisions with other modules. Theme variables (--bg-panel, --text-primary,
 * etc.) pulled from root :root in unified-dashboard.html.
