One form, every result. Enter what you know — each card fills in as soon as it has what it needs. Values persist across the site.
Every card above is live — change any input and the numbers update. Values you enter are stored in your browser only (localStorage) and travel with you to the individual calculator pages, so you never have to re-enter them.
Each card links through to the full calculator for deeper context: personalization panels, charts, category explanations, and the underlying formulas. The summary is deliberately terse — one number and a label per card — so you can scan your whole picture at a glance before drilling in where it matters.
