/* The Market Dashboard panel (showcase/chapters/stocks/_dashboard.html, sd-dashboard.js), the `dashboard` tab of
   the Stocks Data chapter on /how-it-works/.
   One app window with the real page (intrinio_stock/templates/stock_data/market_dashboard.html) condensed into a
   view that scrolls inside itself. Colours inside the window are the page's own: its :root palette (:5-16,
   #22263a to #2a2f45 card gradient, #374151 borders), candles #10b981 / #ef4444, the breadth bar #00c46d /
   #ff4d4d (:240-252), the chart colours (#4CD68F, #E24E4C, #d3d3d3, rgba(105,137,197)), the treemap's #121212
   borders, the selects #2E2E40 / #333754 (:186-194). The panel around the window uses landing.css tokens.
   Everything is sd-dash-* and scoped under .sd-dash. JS state: on the root .sd-dash is-ready (data loaded),
   is-nodata, is-paused, is-still (reduced motion); on the auto label is-idle / is-stopped; everything else is a
   data attribute (data-sd-dash-lamp / -lit / -flash / -dir / -ema-off / -hot), never a class.
   Only transform and opacity animate (plus SVG clip widths, set by the JS). Reduced motion (landing.css section
   13, plus .is-still) and the paused state stop it all. */
