 - **Auto-sell**: optional threshold (shared with bulk sell); on **case opens**, credits are applied after the reel finishes; on **battle wins**, items taken from other players below the threshold are sold immediately
 - **Wear (float)**: each case drop gets a random float `0–1` and paint seed; grades FN / MW / FT / WW / BS (CS ranges). Catalog `marketValue` is the **Field-Tested** reference; instance `valueCents` scales by float within the wear band (FN up to +50%, MW +15–30%, FT mid ≈ catalog, WW down to −40%, BS lower)
 - **Feed Drop**: toggle in nav — live left column of latest case unboxes + MultiPlayers Battle winners
