/* =====================================================================
   TUMRIX STUDIO v0.1 - STUDIO LAYER
   DESIGN PROTOTYPE ONLY. Not production code.

   Deliberately small. Everything this prototype needs already exists in
   the v0.4 theme, which is loaded first:

     ../shiftpocket-v0.4/theme/tokens.electric.css   every colour and size
     ../shiftpocket-v0.4/theme/base.css              resets, type
     ../shiftpocket-v0.4/theme/components.css        cards, buttons, chips
     ../shiftpocket-v0.4/theme/admin.css             rail, metrics, tables

   This file adds only what a multi-app studio needs and the single-app
   admin console did not: application cards, the breadcrumb, the app
   switcher, and the modal used by "Add application".

   RULE, inherited: no literal colour, radius or timing value.
