/* ================================================================
   SportsFathom — the free odds calculators (/tools, backend/api/tools_pages.py)

   A light page of its own: the site's colours (styles.css :root) without
   the app shell, so a calculator opens fast on a phone. System fonts only:
   no web font to wait for. Phone first; a 390 px screen gets one column,
   16 px gutters and no sideways scroll (wide tables scroll inside their
   own box).
