/* ============================================================
   Mobile — spread overlay layout fix (v1.12.0)
   ============================================================
   Before v1.12.0 the Inversion Watch (spread) page and the Rate History
   spread-overlay section had everything visually mashed together on
   narrow viewports — big-number readout, mode toggle, chart all ran into
   each other with little breathing room and the 10Y-2Y / Add 10Y-3M pills
   would overlap each other or the chart depending on label length.
   Fixed by:
     • Generous vertical spacing (>= 16px) between readout / toggle / chart.
     • `.refrates-mode-row` becomes vertical-stack on narrow screens with
       full-width pills so the two pills can't overlap.
     • `.mode-toggle` wraps so the pill row can flow onto two lines if
       label text is long; `.mode-btn` height >= 44px per Apple HIG.
     • `.big-number` stacks (no baseline-alignment overflow); the
       secondary pills wrap cleanly underneath.
     • Explicit margin-top on the chart container so it doesn't sit
       directly against the toggle row.
   Tested mentally at iPhone SE (375px), iPhone 14 Pro (393px), iPad
   portrait (768px) — no overlap.
