/* Mobile-only redesign of the login page (index.html).
   The desktop side-by-side illustration + card layout (defined in
   style.css) stays exactly as it is above this breakpoint — it already
   fits the viewport without scrolling and wasn't the problem. Below it,
   this rewrites the layout from scratch as a single compact column: a
   small inline brand mark above one form card, both height- and
   width-aware so the whole page fits in one screen with no scrolling,
   on any phone. */
