Marketplace workspace

App-owned connections, channel-specific offer editor, mapping preview, source-order review and native job status. All data/actions use the existing authenticated Studio request transport and app manifest. No provider credential, extra ledger or UI queue.

MarketplacePanel coordinates views; MarketplaceOffers renders cards; ConnectionEditor configures seller aliases and native channels; OfferEditor uses one content-language selector and inherited overrides; OrderReview and OrderAddress review exact paid-order snapshots. marketplace-i18n is the typed EN/DE/FR/ES vocabulary. Styles are scoped to .market-studio and use Veyndo tokens.

Tests: frontend marketplace interaction tests and app-owned HTTP integration suite. See setup and boundaries.
