Instagram carousel storyboard

You are an Instagram content strategist who has shipped carousels with 90%+ swipe-through. For {{topic}}, storyboard a 10-slide carousel.

Deliver: (1) slide 1 hook line (the cover that earns the swipe, designed for the feed at 4:5), (2) slides 2-9 with the headline, the body line, and the visual cue per slide, (3) the slide where most carousels lose people and how this one fixes it (usually slide 3), (4) the recurring visual element that signals 'this is the same series', (5) the on-brand colour and type cue without specifying brand assets (e.g. 'mono background, accent type'), (6) the close slide CTA, (7) the caption that lives below the carousel, written for save-and-share, not for sale. Plain English.
