## Best for

A translucent glass card that hazes the star field, orange sun and turning Earth behind it while they stay crisp around it

## Agent notes

- The scene wrapper is pinned with `dark`, so it stays dark in light mode and both `Button` links take the dark token styles
- The sun and the `Planet` Earth are cqw offsets set to straddle the `Card` edge; moved clear of it, the glass hazes only the star grid
- The Earth artwork lives in `EARTH` and its disc position in `DISC` in planet.tsx; change them together for a new photo

## When not to use

- A solid dark banner with the Earth bleeding off the edge and no glass layer: use [Footer Docs CTA](https://web.dev.reui.io/blocks/marketing/cta/cta-8.md) (`get_block("cta-8")`)
- A newsletter join form with an email field over a turning night Earth: use [Release Updates Signup](https://web.dev.reui.io/blocks/marketing/cta/cta-14.md) (`get_block("cta-14")`)

## Install

```bash
npx shadcn@latest add @reui/cta-9
```

## About CTA blocks

### When to use

- A closing get started band with a headline and 1 or 2 actions, some backed by logos, avatars or a rating
- Email capture for a newsletter, a waitlist or release updates, with an inline email field and submit button
- A sales prompt that books a call or opens a contact route rather than a self-serve signup

### When not to use

- The first screen of a page, with the main headline and a product console above the fold: use the [Hero blocks](https://web.dev.reui.io/blocks/marketing/hero.md)
- A compact promo tile with 1 button, sized to sit beside other cards in an app page: use the [Card blocks](https://web.dev.reui.io/blocks/application/card.md)
- A sign in or sign up page with a password, a magic link or social provider buttons: use the [Auth blocks](https://web.dev.reui.io/blocks/application/auth.md)

### Agent notes

- The headline and every action label are written inline in `Cta` in components/cta.tsx, never in a data file; rewrite them there
- No action is wired: every `href` is a placeholder hash and no email form reaches a backend; connect real routes and a submit handler
