Artists not in the explore index had HasPopularity=false and
Popularity=0, making them indistinguishable from confirmed
zero-popularity artists like Shannon Hale. The strict threshold
(60) was filtering all non-indexed MB results.
Now three states:
- Known popular (HasPop=true, Pop>0) → sliding threshold
- Known unpopular (HasPop=true, Pop=0) → strict threshold (60)
- Unknown (HasPop=false) → lenient threshold (15)
Non-indexed MB results are 'unknown' and pass with any reasonable
score. Only artists confirmed to have zero listens face the high bar.
