The prompt

This is the "How Long It Lasts" template from Widget Index. Keep it a How Long It Lasts panel, titled "How Long It Lasts" unless I ask for a different name. Before you build it, ask me only about the parts marked [ask me], one short question at a time, in plain words that fit a How Long It Lasts panel, with two or three concrete options each time. Skip anything you can work out yourself or that has an obvious default. Then build it.

Build me a panel on my Home called "How Long It Lasts".

What it shows: one sentence with the headline (like "14 months of runway at $9.2K/mo burn"), then [ask me: what's left], the rate it goes down ([ask me: the burn], averaged over [ask me: averaging window]), how long it lasts at that rate in [ask me: unit of time], and a line of what's left over time.

Where the data lives: [ask me: where the data lives]. Read it, never move money or change anything. If you can't reach it, ask me to connect or sign in.

Look: make the face of the panel the design, not a list of numbers. One big number up top with a small change pill (green when it's good news, red when it's bad), over a smooth line chart with a soft gold fill underneath. Under the visual, one short insight line that tells me what matters right now (like "Cash lasts to about Dec 2027"), with a dot colored by urgency: green fine, gold needs attention, red act now. Dark background, gold #DEAB42 accent, small title. One visual and one insight on the face; any extra detail goes below it, never on top.

Rhythm: refresh [ask me: how often]. Re-check the source each time and keep only current values; never invent one.
Use: glance.
