Type Alias: PreviewBlockKind

type PreviewBlockKind = "markdown" | "code" | "fields" | "empty";

A single renderable section of a document preview. Documents can produce multiple blocks (e.g. a Soul has SOUL.md + STYLE.md + soul.json), which the Studio renders stacked.

kind is the renderer hint: - "markdown" → MarkdownBlock (prose, headings, lists) - "code" → CodeBlock (yaml, json, plain text in monospace) - "fields" → FieldsBlock (key/value pairs) - "empty" → no body, just the title (used for empty states)
