Add vitest coverage for the session HTTP client and sessions store. Rename the page-local StepActionsList to ExecutionStepActionsList to drop the duplicate component name, and document the Host session memoization contract.

Drop duplicate ExecutionProgress* components and export the canonical ExecutionStatusCard/StatusIcon/useExecutionRows stack instead. Also stop shipping src in the published widget tarball.
Gate the Transak debug logger to development (integrator bundlers dead-code-strip it from production) and drop the wallet address from its payload. Read onError/close/cancel/openDepositFlow through latest refs in the SDK init effect so an unstable callback identity no longer tears down and remounts the iframe mid-session. Document useMeshBalance as a non-wired stub that callers must not gate funding on.
Scan all live pending records (not just the connected wallet's key) in useResumeKey and useIsCheckoutBusy, so a deposit-keyed record stays visible once a wallet connects; add useResumeKey regression coverage. Move the useResumeRecord expiry check into useMemo. Hoist the cash/exchange default source token to a shared constant and document the deny-list assumption. Serve exchange/card funding logos from the @lifi/types assets instead of an external CDN.
Expose remainingMs from useFrozenQuote and drop the duplicate per-second interval in TransferDepositPage. Gate the preview-only deposit-error kinds (which render mocked amounts) to development so production only renders the kinds the status poll actually produces (unexpected, address-expired).
Replace the removed ExecutionProgressCards with a checkout-local component built on the canonical widget execution-status primitives.

ExecutionStatusCard renders motion's m-components, which stay hidden without a LazyMotion feature provider. Declare motion and wrap the checkout execution card like the widget's own execution page.
- Capture linked Mesh accounts (MMT tokenId); show one-tap "Pay with
{exchange}" rows on return, with disconnect to switch
- Persist in sessionStorage per integrator+user with TTL expiry
- Pass theme/language/fiat to Mesh Link; add Mesh preconnect origin
- Pause deposit polling while the on-ramp session loads, not just
while the modal is open
- Catalog-skip needs a backend change, tracked in EXBE-372
- Add opt-in `allowUserDestinationAddress`: user sets recipient in-widget (paste/ENS or connect wallet) when `toAddress` is omitted - Validate against destination ecosystem, persist per integrator - Quote walletless funding using the destination as from-address - Export `useAddressValidation`/`AddressType` from the widget
addConnectedAccounts no longer prunes every integrator's records on each write; it sweeps only the key being written (whole-store hygiene still runs once on rehydrate). Add a regression test.

Which Linear task is linked to this PR?
Why was it implemented this way?
This is PR 7 of 8 in a stacked split of the original
feat/widget-checkoutbranch (formerly the single ~16k-line draft #727). The work is broken into reviewable layers that merge bottom-up intofeat/widget-checkout; each PR targets the branch below it.Two user-facing features layered on the complete flow: reconnecting previously linked exchange accounts, and letting users set their own destination address.
