/* ===========================================================================
   TrackingConsole.css
   ---------------------------------------------------------------------------
   Single stylesheet for the shipment tracking page.

   Replaces MobileView.css + TabView.css + LaptopView.css, which held ~1,815
   lines between them, redefined .inputGroup 65 times and .search 41 times, and
   carried two real defects:

     * a breakpoint COLLISION at exactly 1223px -- TabView ended at
       max-width:1223px while LaptopView began at min-width:1223px, so both
       applied at that width and fought each other;
     * NOTHING above 1800px -- LaptopView capped at max-width:1800px, so wide
       monitors fell back to unstyled markup.

   This file is fluid instead of device-bucketed: one set of rules, a couple of
   min-width breakpoints, so there is no width that is uncovered or doubly
   covered. Colours and spacing come from tokens declared once in :root.
   =========================================================================== */

/* ---------------------------------------------------------------------------
   Theme.

   Dark is the default for this page -- it is a working tool staff keep open all
   day. The header toggle writes data-theme onto <html> and the choice is
   remembered in localStorage.

   Every colour is a token declared here, so a theme swap only redefines tokens
   and no component rule needs to know which theme is active.
