+### Workspace copy cleanup — follow-up to #28
+
+At the user's request, removed repeated demo/preview banners from the workspace,
+transaction forms, auth, email confirmation, identity and limits. Confirmation
+and result copy now uses ordinary product wording in EN/RU; the mobile wordmark
+remains without the extra note. Removed unused localization entries and duplicate
+email-state copy. Existing journey measurement, simulation flags, service behavior,
+funds explanations and recovery controls are unchanged. Development constraints
+belong in this record and package README, not repeated throughout the product UI.
+
+Delivery continues in [PR #29](https://git.sendico.io/tech/sxchnge/pulls/29) on
+`workspace-28`. This copy change does not connect real authentication, email,
+payment, support or backoffice services.
+Validation: all 115 frontend tests, app analysis, app Dart formatting, web build
+and diff checks pass. Updated existing copy expectations; telemetry tests still
+verify simulated events never count as real business success. No new click events
+were needed for this presentation-only cleanup.
