   Breakpoint Reference Constants (documentation only)
   ------------------------------------------------------------
   CSS custom properties CANNOT be used inside @media queries,
   so breakpoints are fixed pixel constants. These values are the
   canonical breakpoints for BOTH hosts — keep any @media rule in
   app.css aligned to exactly these widths:

     --bp-sm   : 576px   (small / large phones)
     --bp-md   : 768px   (tablets / mobile-desktop boundary)
     --bp-lg   : 992px   (desktop)
     --bp-xl   : 1200px  (wide desktop)
