Patterns for answering questions about the user's Sana card — metadata (status, last4, expiry), spending power (limits, charges, balance due), card transactions, full card number + CVV on explicit request, and guiding a user through end-to-end card registration and usage. Load this when the user asks about their Sana card, what they've spent, how much they can still spend, their full card details, or how to get/use a card. Requires the using-sanabot skill for connection/error handling context.
