ux-scenarios — Maintain the Scenario Base

Part of super-ux — see system-map.md for the whole pipeline and the four sync rules. After changes, run the linter (python3 docs/ux/lint.py).

AI-generated interfaces go bad when UI is built without a model of user behavior. This skill keeps one: docs/ux/scenarios.md in the target project is the source of truth for everything the user can do, see, and hit — every feature, every button, every state, every error, every result.

Format contract: scenario-format.md (ux-contract v4). Read it before writing or editing scenarios. Never deviate from its field names, ID rules, statuses, or checklists.
