/* ==========================================================================
   HARP Platform - application styles

   The design language is inherited from the Freethinking Group system already
   used by Budget Planning and the potent.ai portal: Montserrat, the TFG
   secondary palette, teal accent, generous card radii, soft shadows on a light
   dot-gridded working surface.

   Two deliberate departures, both because this is a reporting workspace rather
   than a linear tool:

   1. Navigation is a persistent left rail, not a top bar. There are nine
      destinations here against Budget Planning's two, and a rail also leaves
      the full width of the header free for the context bar.
   2. Density is higher. Type steps down a notch and table rows are tighter,
      because the job is reading hundreds of rows of booking data rather than
      filling in a short form.
