PARTIAL SAVE: writes ONLY the 'Workshop' field of TitlePublicConfigurationModel; all other v1/v2 fields stay untouched. Workshop - the catalog of content made by PLAYERS (maps, levels, skins, models, any file the game defines) and by the publisher (official content), and the LICENSES to it. Nothing is transferred: acquiring grants a license to a digital copy, so one publication is acquired by many and the author keeps it (unlike Marketplace, which escrows and moves goods). ContentTypes is the game-specific part: each type id (e.g. 'voxelcraft.world') declares its file roles (AllowedMimeTypes, MaxBytes, MaxCount, Required; the engine checks the uploaded file's signature against the declared type), whether a thumbnail is required, which AccessModes authors may use, an optional per-type PricePolicy, a PublishGate (SegmentGate: who may publish), PublishFeeOptions (PriceOption, Standard part only, never store-paid), a TagVocabulary and per-player limits. An author gives access by ANY of several options: Free, Price (a ResourceBundle validated by PricePolicy; the buyer pays, the author receives it minus Commission, which is burned or credited to the MarketplaceLedger) or Holding (hold N of a currency/item - nothing is charged; Mode WhileHeld re-checks on every download, UnlockOnce checks once and grants a permanent license; HoldingPolicy whitelists usable resources). Moderation: BlockedTerms for titles/descriptions/tags, AutoHideReportThreshold (reports that hide a publication until reviewed), RequireApproval (pre-moderation). Featured lists publisher-curated collections with their own ScheduleSpec and SegmentGate. Publications, licenses, reactions and reports are NOT here - they are operational data in their own collections; files live in a private bucket configured by the engine's WORKSHOP_BUCKET_NAME env var.
