FORCDK-CAROUSEL-002
Warned by forty-cdk/carousel, in development builds only.
[forty-cdk/carousel] FORCDK-CAROUSEL-002: {indicators} [forCarouselIndicator] element(s) are registered for {slides} slide(s).Cause
The picker targets slide i from the indicator at DOM index i, so a mismatched count desynchronizes the active-indicator state.
Fix
Render exactly one [forCarouselIndicator] per [forCarouselSlide].
