MARKETING.md says what Steam rewards (purchases and playtime, never page traffic or wishlists), so the plan is three loops — coming-soon wishlist accumulation off the reel factory, the launch email, update rounds. Valve's partner Web API has nothing for the page or events; it has exactly two marketing reads, GetAppWishlistReporting and GetDetailedSales, and bin/wishlists.mjs pulls both into the vault. store-page/fill.md walks the partner editor field by field with the value or file for each.
