✨ New
- Automatic language detection: if your browser is set to Spanish or Portuguese, the app and landing page load in that language from your first visit. No more digging through settings to switch from English.
- Redesigned profile dashboard: your profile opens on a single metrics card: - total P/L, daily average, best day, worst day. Toggle between USD and sats, filter by trade type. The Performance card flips between the P/L chart (restyled) and a new P/L calendar with daily totals, tap any day for the details. Works the same on desktop and mobile.
- Settings got their own page: with five tabs - account & security, device & session, verification, preferences, communication. On mobile, each edit opens in a bottom drawer. A few things we added along the way: sessions show how long they've been active, the authenticator QR code sits above the secret key, and you can link, edit and remove multiple Lightning wallets.

- Lightning node page: live stats for our node - public key, connect URI with one-tap copy and a QR code, capacity, channel count, channel sizes and ages. The Explore menu points there now instead of an external site.

- Isolated calculator redesign: full-width side selector, liquidation and P/L in their own cards.

🐛 Fixes
- CSV exports (deposits, withdrawals, addresses, swaps, funding fees, orders, transfers, closed trades) now start downloading immediately and no longer stall on large histories, timestamps are consistently ISO UTC.
- Icon-only buttons and links now carry accessible labels for screen readers.
- Design polish across the app: pricer spacing, the Cross account card title, a consistent 4px gap above the footer, wallet history amounts sized like the rest of the app, a back button on the Swap page with its ratio buttons closer to the submit button, and updated tab padding.
