Overview
The Tech Preview pattern communicates to users that a feature is in a preview or beta state and not yet ready for production use. It consists of two main components:

Tech Preview Badge: Located in tab navigation adjacent to the feature name
Warning Banner: A dismissible information/warning banner that clearly states the feature's limitations
This pattern helps set proper expectations for features still under development or testing while allowing users to explore new functionality in a lab environment.
Best Practices
Consistent Placement: Position the Tech Preview badge at the appropriate level in the navigation hierarchy
Clear Communication: Use straightforward language to explain the feature's preview status
Visual Distinction: Maintain consistent styling for all Tech Preview indicators
Banner Visibility: Ensure the warning banner is prominently displayed when accessing the feature
Appropriate Hierarchy: Place the badge at the highest logical level in the navigation
Dismissible Warnings: Allow users to dismiss the warning banner after reading
Complete Coverage: Include the badge on all relevant entry points to the feature
