The carousel iframe row was wrapped in {#key currentIndex} with
transition:fade, so switching slides (or navigating to the page) faded
the old and new row in overlap — briefly showing two rows / a blink.
Drop the fade from both iframe containers, matching the modal variant
which uses {#key} without a transition.
