/* =========================================================================
   TradeKit Marketing — the blog's chart demos

   The framed screens the demo shortcode prints into a post
   ({% demo "breakout" %}, eleventy.config.js) and js/blog-demos.js plays:
   a trigger order on a little candlestick chart, drawn the way the app's
   chart draws it. post.njk links this file on posts that have a demo, and
   the homepage for its trigger-orders reel (at the end: the homepage's
   chart demo, then these, in one screen).

   The frame is the homepage's .tk-screen at the blog's volume: an ink
   border, a HUD bar, the category's plate. It runs the article column's
   full width, like the cover, rather than the text's measure. Inside,
   every color is a palette role, so every theme re-inks the chart live,
   and sizes are px: the chart draws at its real size, its type at the
   chart's 10px (11px on a wide screen: --bd-fs, set by the script, with
   --bd-chip-h).
