- Make CodeBlock a server component so children traverse synchronously
under React 19 RSC streaming; previously extractText returned "" in
dev SSR, leaving code blocks empty.
- Add custom JSON/YAML/SQL/code-like tokenizers with theme-aware token
classes; drop the colored file-glyph dot and gradient tab-head.
- Tighten tab-head: subtle grey background, smaller monospace filename
in muted grey, smaller rectangular language pill placed to the left
of the filename.
- Polish the React Flow semantic-layer diagram (controls, fit-view
padding, edge types).
* docs: streamline quickstart
* feat(docs): simplify quickstart code-block styling
Remove the fake terminal chrome (traffic lights + zsh header) and language
pill from bash blocks, and the teal left-accent from output blocks. Bash
fences now render as minimal cards; text fences route to a muted "output"
preview. Make detectLanguage recursive and enable addLanguageClass in
source.config.ts so Shiki tokens carry through to the renderer. Switch
Shiki themes to min-light / github-dark and disable monospace ligatures so
flag pairs like --agents keep a visible space.
* fix(docs): restore quickstart CI snippets
