Instead of fixed 20 RGs + 100 recordings for every artist, scale
the budget by popularity using a power curve (exponent 0.3):
Radiohead (2.5M listens): 20 RGs, 100 recordings
Hans Zimmer (715K): 15 RGs, 71 recordings
Clutch (178K): 11 RGs, 50 recordings
Similar (~10K): 7 RGs, 27 recordings
Organic (unknown): 5 RGs, 10 recordings
Saves ~53% index size (~29 MB vs ~62 MB) with identical API calls.
The savings come from T4 similar artists (long tail) where full
discographies were wasteful. Top artists still get full coverage.
