Port the full docs routing + rendering infrastructure from the 4084
branch (atai/2026-04-17/internal-showcase-followups):
- New [framework]/[[...slug]] catch-all that validates the first
segment against the registry and renders framework-scoped docs
with a "not available for this framework" banner when the page's
defaultCell is not tagged in the framework's cells.
- FrameworkProvider + selector: framework is strictly URL-derived,
storedFramework is an advisory localStorage signal. No
auto-redirect from localStorage.
- /docs/[[...slug]] rewritten as a thin wrapper around DocsPageView
with a new DocsOverview landing: framework picker + topic cards.
- New lib/docs-render.tsx centralising snippet inlining,
frontmatter parsing, nav tree + breadcrumb builders.
- New lib/mdx-registry.tsx consolidating the ~700-line component
shim used by both routes.
- Server <Snippet> component with demo-content regions + syntax
highlighting via highlight.js.
- Per-feature <InlineDemo> iframe embedder pointing at the
integration's backend (single-container shape
http://localhost:3100/demos/<cell>).
- FrameworkTabs, docs-callout, docs-steps, docs-tabs, router-pivot,
stored-framework-highlight components for the MDX registry.
- Global typography + color pivot in globals.css: Plus Jakarta
Sans body, Spline Sans Mono code, cool-gray background, purple
accent.
