Carousel benchmark

Give me a niche — I return the carousel accounts that win there, ranked by organic quality, with the formats that carry them and a slide-by-slide read of the best posts. Made by @nestymee while launching a carousel account; the tricks below are what a full day of scraping taught.

# 1. discover (Top search — the only search that returns carousels)
python3 ../../tools/carousel_scan.py --queries "digital closet app" "apps every girl needs" --per-query 30 > search.json
# 2. profile-scan the candidates (≈$0.003/post on Apify)
python3 ../../tools/carousel_scan.py --profiles handle1 handle2 handle3 --per-profile 25 > profiles.json
# 3. rank
python3 ../../tools/carousel_leaderboard.py --in profiles.json --min-slides 5 --md leaderboard.md
# 4. look at the slides of the top posts
python3 ../../tools/carousel_scan.py --posts URL1 URL2 --slides-dir slides/
