-1. Low-follower quarantine: Scraped IG < 10,000 without verified override is treated as unverified (NaN),
-   preventing secondary/fan handles from dragging down veteran artists.
-2. Neutral weight scaling: Prevents artists with missing signals from leapfrogging artists with verified data.
-3. Strict zero-imputation & provenance tracking preserved.
