/* ---------------------------------------------------------------------------
   Tracker — dark, mobile-first.

   Design rule this file follows: exactly one layer of visible structure.
   Grouping is done with space, not with borders and panels. A hairline is
   only allowed where two rows would otherwise touch ambiguously. Exactly one
   element on screen carries weight — the verdict on Check, the day's PnL on
   Wallet. Everything else recedes so those read in a glance.
