hosttech-GmbH/laravel-slack-block-kit-builder ? reverse-engineered prompt

Build me a Laravel package that helps me create Slack Block Kit payloads in a clean object oriented way.

I want to be able to compose Slack messages from reusable objects instead of hand writing big arrays, then turn them into the final payload I can send to Slack. Please make it feel natural for Laravel projects, with good defaults, easy to read code, and solid tests so I can trust the output. If it makes sense, include a simple way to build common Block Kit pieces and combine them into a message without a lot of boilerplate.

Keep it lightweight and practical, and make sure the package is ready to install through Composer. If you need to check current Slack Block Kit docs or Laravel conventions, look them up online and follow the current behavior.
