 The landing page hero now reveals elements in a staggered sequence: title animates in, followed by CTA and stats, then feature grid. This creates visual hierarchy and guides user attention through the landing experience on first load.

 Order cancellation now operates on a single order with full transactional integrity. The contract validates that only the specified order is affected, preventing accidental batch or partial cancellations. A confirmation dialog and explicit completion toast confirm the action to the user.

 Progress toasts for in-flight transactions now stay visible until the user dismisses them or a terminal outcome arrives. Terminal outcomes (success or error) are auto-dismissible but can be manually closed for faster clearing. This gives users full control over transaction visibility while maintaining clear completion signals.

 Transaction toasts now include contextual recovery actions: retry, cancel, view on explorer, and view account. Links to Stellar Expert provide transaction verification and debugging, while recovery actions guide users back to incomplete workflows.

+The Funding & Fees tab now shows complete fee and funding activity with explicit token symbols, timestamps, and accrual versus settlement status so entries cannot be confused with trading PnL. Claim actions appear only on settled funding rows where the contract supports them.

+Deposit and withdrawal buttons are now disabled with a clear explanation when the OrderVault contract is not deployed on the current network, preventing any action from silently reporting a successful transfer from a no-op stub.

+The trading page now pauses non-essential data work when the browser tab is hidden or offline, and revalidates active market and account data on return, preventing stale execution estimates and stopping offline actions from silently queueing financial submissions.
