/* ===========================================================================
   EduVoice CRM — visual language

   A working console, not a landing page:

     · a dark navy rail on the left that never moves, so navigation is muscle memory;
     · a light working area where data is dense and quiet;
     · one accent — amber — only for what the eye must find: the active section, the
       primary action, the number that matters;
     · three status colours that never change meaning anywhere in the product:
       green = the assistant handled it, orange = a person is needed, grey = dropped.

   Every interactive element is built from the same measurements. `--control-h` is the
   single height of buttons, inputs, selects and segmented controls, so a row of mixed
   controls lines up without a single inline style. Templates never carry `style=`.

   Motion is functional: 120 ms on hover and focus, 400 ms for a chart drawing itself,
   nothing that moves without a reason. All of it is off when the operating system asks
   for reduced motion.
