/* ------------------------------------------------------------------
   app.css — Progress Monitor Field App
   ------------------------------------------------------------------
   Written for a gloved hand in daylight, not a mouse in an office.

   - Minimum tap target 52 px; primary actions 60 px.
   - No hover state carries meaning. Nothing needs a right-click.
   - Contrast is deliberately high: body text sits at or above 7:1 on its
     background, status chips above 4.5:1, because the screen will be
     read outdoors at an angle.
   - Layout: tablet shows model and list together; phone shows one at a
     time with a fixed switcher. Both work in portrait and landscape.
