This is a dev working home — not a showcase. It's the place you come back to when you're building with the Platform: what exists, what changed, and how the pieces fit. If it's your first visit, this page is the on-ramp; after that, the hub is your resting state.
A growing set of composable tools and the recipes that stitch them together. Everything here is derived from a manifest, so what you read is always what's actually shipped — the catalog can't drift from the collection.
Every count, every list, every "what's new" line on this hub is a fold over a source-of-truth manifest, re-derived on each build. When a rendered page and its source disagree, the source wins — and a gate refuses to ship a page that drifted.
site/platform/orientation.html, rendered from the section frame + the manifests by build_habitat_pages.py over page_set.py. The source is canonical; when a rendered page and its source disagree, the source wins.
