HYBRID CORE 5.1.0-0922-02 — UNIFIED TWO-PRODUCT NAVIGATION

- Sidebar entrance is reduced to 1- Hybrid Core.
- Core opens one management shell with a top selector and one changing content frame.
- Boards & Hierarchy, Connections, Users & Access, Workforce, Secure Portal, Settings and optional QA remain reachable without separate competing sidebar entries.
- Installed engines are not renamed or removed; controller, folder and table compatibility is preserved.
- 2- Hybrid Boards remains the separate operational entrance.
- No database migration.

Staging QA required: menu rendering, same-origin frame styling, every selector target, CSRF forms inside the frame, direct-page fallback and responsive selector.
