## Best for

A dark violet band where looping neon sine lines scroll behind a 2 line headline, a lede and 1 pill button

## Agent notes

- The 30 sine lines are generated by `STREAMS` from `STREAM_LINES` and `STREAM_POINTS`; change those constants to thin or thicken the field
- The scroll is a 22s CSS loop in `STYLES` that stops under reduced motion; change its duration there
- The violet base, scrim and inks are fixed oklch values on the `Card`, not theme tokens, so the band looks the same in light and dark

## When not to use

- A still gradient band with a headline and 1 button and no moving backdrop: use [Headline Only CTA](https://web.dev.reui.io/blocks/marketing/cta/cta-5.md) (`get_block("cta-5")`)
- A centered pitch with an eyebrow badge, 3 proof tiles and 2 buttons: use [Proof Grid CTA](https://web.dev.reui.io/blocks/marketing/cta/cta-4.md) (`get_block("cta-4")`)

## Install

```bash
npx shadcn@latest add @reui/cta-6
```

## 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
