   Workout Tracker — rossoneri
   Palette: AC Milan red #FB090B, black #0A0A0A, white, gold accent #D4AF37.

   The shared shell — tokens, top bar, panels, inputs, buttons, tabs, report,
   toast — is carried over from Weight Tracker so the two apps feel like one
   pair. Everything below the "workout" divider is new: plan rows, the lift
   session runner, the treadmill display and the bottom sheet.
