Call to action

Add it to your project

Run the command — it writes components/blocks/cta-03.tsx and leaves the rest of your project untouched.
```
npx astralis-cli add cta-03
```
Import it where you need it. The block only depends on astralis-ui, so it compiles in any React project — no extra packages, no framework lock-in.
Edit it. The copy, links and layout are plain JSX in your repo now — this is your file, not a dependency to configure around.

Composes Box, Button, Container, Flex, FlexItem, Heading, Input, Link, Stack, Text.
