Curated star-player insert (e.g. Ben Simmons, LeBron James, Zion Williamson, Luka Doncic), randomly inserted per hobby box. Count of 20 confirmed by tcdb's full card-level checklist and independently matched in prose by cardboardconnection/checklistcenter; Panini's own first-party blog preview states "25 of the top current players" (single-source outlier, rejected per card-level tcdb checklist -- see gap G-003). No print run or serial numbering published anywhere found. Marketplace/eBay listings label individual Downtown cards "SSP" but this is marketplace copy, not manufacturer-stated odds, and per spec is not usable to tier -- not tiered in the scarcity pass (see scarcity_sets.csv).
