/* Desktop / tablet layer.
   ------------------------------------------------------------------------
   app.css is the mobile baseline and is never touched below; everything here
   is additive from 640px up. The web build stops being a stretched phone at
   1024px: the bottom tab bar becomes a fixed left sidebar, content gets a
   centred measure, and the equipment feeds become a 3-4 column card grid.

   The layout hangs off one structural trick: `.ph:has(> .nav)` distinguishes
   an in-app screen (sidebar + dashboard chrome) from an onboarding screen
   (centred auth panel), so no screen has to declare which shell it wants. */
