/* ==========================================================================
   LebCoin Wallet

   The explorer is a public reference and reads as institutional. This is
   personal money, in a country where institutional trust collapsed — so it is
   built to feel solid and tactile instead.

   The balance card is the one bold element: a banknote. Hairline border, cedar
   watermark, and the figure set in a serif rather than the geometric sans that
   every crypto wallet reaches for. Everything else stays quiet.

   Flag red appears only for locked state, destructive actions and errors.
