/* ==========================================================================
   Phantom — application layout
   ==========================================================================
   Two levels, as the brief asked for:

     1. Launchpad  — no chrome. Pick a project, or create one.
     2. Project    — persistent header with tabs. Everything is scoped here.

   There is no global "overview" competing with the project. When a tool is
   scoped to a project, a cross-project dashboard is just a hop between the
   user and the thing they came to do.
