/**
 * Maximum decoded summaries retained by each `(family, step level)` cache.
 *
 * Step summaries grow with their frame size, so the limits decrease at higher levels. Block
 * summaries use a tighter schedule that keeps roughly 4,000 hydrated blocks at each level
 * (512×7, 128×31, 16×211, or 2×2,311). Aggregate summaries are substantially smaller, but use
 * the same bounded-per-level shape so a historical scan cannot populate an unbounded family cache.
