/* ==========================================================================================
   Contact Archive — mobile-first stylesheet (owner: ui)

   Rules of the house:
   * No external fonts (system stack only), no imports, no url() to anywhere.
   * Light and dark via prefers-color-scheme; both themes use the same tokens.
   * Touch targets >= 44 px (--touch). Base font 16 px so iOS never zooms on input focus.
   * Animations/transitions only on transform/opacity/colour (never width/height/top/left),
     so scrolling and typing never trigger layout thrash.
   * 360 px is the narrowest supported width; a 420 px+ breakpoint adds desktop niceties.
