   Tiering:
   - < 576px  (phone):        off-canvas drawer, hidden until toggled open (full width)
   - 576–1023px (split-screen/tablet): ALWAYS visible as an icon-only rail;
                               toggle expands it to the full labeled sidebar as an overlay
   - >= 1024px (desktop):     ALWAYS visible full width by default;
                               toggle collapses it down to the icon rail (pushes content)

   NOTE: rows use flexbox (not grid) so the icon can be truly centered when the
   label collapses, and labels collapse via max-width (which animates smoothly)
   rather than width: auto <-> 0 (which does not animate reliably).
