Obsidian & Ember design overhaul
The renderer and both native windows move to the new MyQRLWallet design system, matching qrlwallet.com:
- New visual language: deep warm-ink surfaces with layered ember glow and grain, ember orange as the single action color, QRL battery blue as the identity color (address pill, transfer From address, table headers).
- Typography: self-hosted Sora (display), Instrument Sans (body), and JetBrains Mono for addresses, balances, and seeds.
- Unified glass card treatment, staggered page entrances (with prefers-reduced-motion opt-out), restyled sidebar/dock/footer, mnemonic words as numbered chips.
- Native unlock and settings windows retokened to match the renderer.
No changes to key handling, signer isolation, IPC, or the security model. Binaries are unsigned; verify with SHA256SUMS.
Full changes: myqrlwallet-frontend#230, myqrlwallet-desktop#25, #26, #27.
