How it works: fold moving/housekeeping into Spending & Savings, drop SP

One card instead of three: the analogy, what runs Spending (Ark +
Lightning) in plain words, and a single paragraph covering Move money,
fees, automatic upkeep, and the pre-signed escape route. The silent
payments section goes — no user-facing SP receive mode exists anymore.

Savings is ordinary Bitcoin on the blockchain — the safest place for money you’re keeping, but every move costs a mining fee and waits for a confirmation.

     hiwLn2: 'Under the hood, Spending runs on Ark, a newer layer built on top of Bitcoin. Your Spending balance sits in a shared pool coordinated by a coinos server, but every coin in it is locked to your key — the server can’t move a sat without your signature. Spending also speaks Lightning, the payment network most bitcoin apps and shops use, so you can pay any Lightning invoice and anyone on Lightning can pay you.',

Behind the scenes this uses Ark and Lightning, but you never have to think about either.',
