/* NYL Charts — Synthwave Trading Terminal
 *
 * Design language:
 *   • Midnight-navy base with subtle horizontal grid scanlines
 *   • Cyan-blue (calls / bullish) + hot pink (puts / bearish) duality
 *   • Glassmorphism on floating panels — backdrop-blur + low-opacity bg
 *   • Animated gradient borders on focus / active states
 *   • Geometric ticker pills with sliding accent indicator
 *   • Slide-in settings drawer (right edge), no more centered modal
 *   • Pulse-glowing live status indicator
