Summary

• Get Updates card: 460px wide (was 420px), so the note under the email field fits on one line on desktop.
• Card copy: the intro reads "Marfa is being built with a small group of early testers. Leave your email to hear when the apps open to everyone." The note reads "Only news about Marfa. Unsubscribe any time. Privacy", which matches what the privacy page promises.
• Header: 14px above and below the controls on desktop (was 18px), 12px on phones.
• Footer: About and Subscribe only. The privacy notice is still linked from the sign-up card, where the address is collected, and from About's closing line ("Read the privacy notice"), so anyone can find it. It also stays in the sitemap.

Testing

• pnpm check and pnpm build pass.
• Checked locally at 1440×900 and 375×812, in light and dark. The card note is one line on desktop. About's closing line is one line on desktop and two on a phone.
