Seven Envelopes - if the cards stopped working for a week

A card-down week planner and rainy-day layer check. List the cash your household would still need if card payments, phone wallets and banking apps stopped working for a week - what, amount, when - and see seven day envelopes, Monday to Sunday, fill in order from the cash in the tin, with the day it runs dry and the shortfall. Put your savings in layers (tin, instant-access, notice, longer-term) and see them in months of essentials against a rule-of-thumb range for your kind of income (estimates, not advice). One metered run writes the plan: a verdict by a fixed rule (exposed, thin, ready), the lines that could shrink for a week, what each layer is for, the next moves in time order and what to watch out for; the page re-checks every reply and exports a printable cash list.
