gs_04_first_base

Audience: users with a small linked graph who have not yet marked a base.
Outcome: create a base ( `.reqlan` ); explain that a base is the boundary of one ideas graph and owns the ideas index; know extension install ≠ base create.
Runtime: 5 – 6 min.
Demo: `reqlan-tutorials-demo` with `reqs/product.rq` containing linked `welcome_flow` ↔ `onboarding_checklist` ( and optional `account_model` ). No `.reqlan` folder. Activity bar or Ideas Summary shows empty / create-base prompt. Caret on any idea in `product.rq`.
