I made a printable double-sided Letter PDF for handing a loaded SATSCARD to a non-technical family member.

It is written at a plain 5th-grade reading level and includes:

• a simple River -> Nunchuk on-chain loading route
• a Lightning -> Bitcoin swap route using Boltz
• a final safety checklist before handing the card over
• explicit warnings that the physical card controls the funds
• the requested wording: "not-your-key-card, not-your-bitcoin"

I can revise it if you want the guide adapted to a specific wallet/exchange flow.
