/* ==========================================================================
   Features page (features.html, i18n/ar/features.html)

   Loaded after site.css. Page top on a dotted background with "Jump to"
   pills, then the feature sections grouped Build / Backtest / Analyse /
   Deploy. From 992px a section list sits beside them: it scrolls with the
   page until it reaches the header, then sticks; toc.js highlights the
   section being read.
   Phones: each section stacks kick, title, screenshot, then the text.
