   M-WALLET  ·  ZEVARYN GRID
   ZG1 — Global Design Foundation
   Zevaryn Systems

   Modular. Intelligent. Yours.

   This file is loaded AFTER css/style.css and css/m-cash.css.
   It re-skins M-Wallet into the Zevaryn Grid design language by:

     1. Defining the Zevaryn token system (--z-*).
     2. Re-mapping the existing legacy tokens (--bg, --surface,
        --charcoal, ...) onto Zevaryn values so the entire app
        inherits the dark / violet / teal identity automatically.
     3. Patching the handful of places that used hard-coded
        light colours instead of tokens.
     4. Providing reusable Zevaryn components (.z-card, .z-grid,
        .z-btn, .z-input, .z-badge, .z-progress, ...) for the
        later page-specific phases.

   No financial / business logic is touched. No IDs or data-*
   attributes are changed. Selectors mirror the originals so the
   cascade — not !important — resolves the override.
