Version slider & generated roadmap

Drag from MVP to v5 and watch the same site re-filter live. The roadmap is a generated page, not a promise.

Every feature’s frontmatter records the version it first ships in — a fact, set once at the roadmap session (Gate 2). The slider is pure client-side state (?v=mvp): screens and page sections conditionally render against it, so dragging MVP → v1 → v5 re-filters the same content live.

The v5 view stays up as the north star. The current-version view is the spec handed to each build slice. And the roadmap page — shipped, next, and blocked-by-which-decisions per version — is generated from frontmatter, so it can’t drift from reality.
