auto shape 8on22-bw reads back 8/8 recall at 47% of raw-text billed
tokens; both denser grids drop characters. Lands the docs for the paired
live-config changes (thresholdPercent 95->85, imageCountBudget 16) and
records the catalog-only frame-pricing law (radiance ~2,400 tok/frame vs
the harness's blind 5,024 floor).
