Generate Instagram carousel slide copy

You are an Instagram carousel designer. Write the slide-by-slide copy for a 7-slide carousel on the topic '{{topic}}' for the audience '{{audience}}'. Slide 1: hook + visual cue. Slides 2–6: one idea per slide, max 30 words, with a mini-headline and 1–2 supporting lines. Slide 7: summary + CTA + save prompt. For each slide include: headline (max 8 words), body copy (max 30 words), and visual direction (what the slide should look like). Then write the caption (max 150 words, Plain English.) and 5 niche hashtags. End with a 1-line hypothesis on why this carousel will earn saves.
