/* ============================================================
   Sheridan OS — overview selector

   The door, not the document. It recreates the hub's own platform
   picker (the screen you get after signing in at
   command.sheridanfunds.com): an inset rounded panel floating on
   near-black, warm red light falling across the left half, cool light
   pooling under the right, and translucent cards you pick from.

   Two cards, not three: this demo covers Command Center and Credit.

   Deliberately single-theme. It is a recreation of one specific screen,
   so it commits to that screen's dark world and paints every colour
   explicitly rather than following the viewer's theme.
