A small, brand-neutral control layer helps selected operator interfaces behave consistently without making House Desk and Pub look like one product.
The shared contract covers ordinary control behavior—focus, keyboard operation, dialogs, form state, feedback messages, and progressive enhancement. Each product still owns its visual identity, information architecture, permissions, and release schedule.
Public guarantees
- Real form controls remain usable without decorative JavaScript.
- Keyboard focus is visible and dialogs return focus when closed.
- A product pins and reviews a version instead of receiving silent changes.
- Shared code contains behavior and neutral tokens, not one tenant’s brand.
- Server authorization remains independent of what the interface hides or shows.
Implementation and release procedures are maintained in the private package and product repositories.
