/* ===========================================================================
   GPS lap timer page.

   The standalone pages' dark graphite (install.html, the generated pages),
   restated here rather than inlined because this page has state to style.
   Mobile first; 720px is where the masthead nav comes back, as everywhere.
   Rules from CLAUDE.md that bite here: targets >= 44px (the Start button is
   much bigger, it is pressed in gloves), inputs >= 16px, wide tables scroll
   in their own box.
