/* ===========================================================================
   Sal's Kewl Korner customer panel
   ---------------------------------------------------------------------------
   MOBILE FIRST, and meant literally: every base rule here is the phone layout,
   and the media queries only ever ADD width. The panel is opened on a phone at
   least as often as on a desk -- checking a customer while away from it is the
   normal case, not the exception -- so the narrow layout is the one that has
   to be right, and the wide one is the enhancement.

   What that means in practice, and what to preserve when editing:

   - Nothing has a fixed width. Tables become stacked cards under 720px rather
     than scrolling sideways, because a table you have to pan is a table you
     cannot read on a phone.
   - Tap targets are 44px minimum. That is the size a thumb actually hits.
   - Inputs are 16px. Anything smaller makes iOS Safari zoom the page on focus
     and then leave it zoomed, which feels like the page broke.
   - Colors are tokens, defined light and redefined for dark. Never hard-code
     a hex where a token exists -- it will be wrong in one of the two themes.
