   Evidence Data Migration — application layout
   ----------------------------------------------------------
   Loaded AFTER the Solidrange kit (tokens → components →
   animations → icons). Adds only what the kit does not ship
   (app shell, sidebar, closable instance tabs, toggle,
   multi-select, stepper, alerts). Every color, radius,
   spacing, shadow and duration is a kit token — no brand
   hex values are hardcoded here.
