- Wide desktop (≥720px) now renders a left sidebar nav (Wallet/Activity/Send/
Receive/Settings) with a profile card instead of the bottom tab bar; narrow
screens keep the bottom tabs. Both drive the same Tab state and screens.
- Settings gains an Appearance group: tap to cycle theme (Dark/Light/Yellow,
re-applies egui visuals live) and density (Comfy/Regular/Compact).
