/* ==========================================================================
   Fey — the commercial admin's own shell and its charts.
   --------------------------------------------------------------------------
   Everything underneath this file is the shared design system: the tokens, the
   components, the type scale. What lives here is the furniture this app does
   not share with the product — a darker rail, a denser page — and the chart
   primitives, which only exist where there are charts.

   The charts are HTML, not SVG, and that is a decision rather than a shortcut:
   bars made of boxes reflow with the page, their text stays crisp at any zoom,
   and every bar is a real hover target without a hit-testing layer.
