Tap → unlock took ~3 s on sintra. The card server's /session now fills
fiat only from its warm rate cache (aiolabs/boltcards
fix/session-fiat-from-cache); when it returns a currency with fiat null,
the store prices the balance in that currency from the ATM's own rate
source after the unlock, so the chip still shows the wallet's currency.
Log how long the session call took and whether the server priced it, so
the next latency question can be answered from the journal.

At Complete the store handed the session's withdraw/pay step to
window.electronAPI straight out of the loadedBoltCard ref — a Vue
reactive proxy — and Electron's structured clone refused it:
'[ATM] Bolt Card withdraw failed: Error: An object could not be cloned.'
(sintra, 2026-09-21 06:51). The customer had to re-tap, which works
because the direct-tap path passes a plain string. Copy the steps field
by field into plain objects before they cross the bridge.
