Code Review

This pull request introduces a new SiCarouselComponent and updates the CriterionDefinition interface in the filtered-search module. The review feedback identifies a style guide violation regarding the use of effect() for state propagation, suggests removing non-idiomatic 'this.' references in Angular templates, and highlights several UX writing guideline violations in the carousel example component, specifically regarding capitalization, vocabulary, and the use of abbreviations.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

I think the handling of multiple fast presses of the next/prev buttons is not ideal. I guess the moving should just accelerate and not replay until all clicks are processed. When operating with keyboard and the focus is on the entire carousel, subsequent arrow key presses are just dropped. The should not be.

• fast clicks now accelerate moving.
• we are not explicilty handling arrow keys interaction and behavior is default with scroll-snapping css (see https://developer.mozilla.org/en-US/docs/Web/CSS/Guides/Overflow/Carousels)
