Invisible state connector atom — no visual output. Initialises window._A2UI_STORE and dispatches "a2ui:store" CustomEvent. On GAS reads initial state from a Google Sheet at render time and writes back async via google.script.run. On web reads/writes localStorage keyed by course_id. All other LMS atoms read from and write to this shared store. Must appear before any stateful atom on the page.
| Field | Type | |
|---|---|---|
| course_id | string (required). Unique course identifier — scopes the Sheet and localStorage key. | required |
