/**
 * Pure (React-free) part of the standard `code` block: its data schema and MDX
 * round-trip config. Shared by the server MDX adapter (a plan/content app
 * registers it via `@agent-native/core/blocks/server`) and the full client spec
 * (`code.tsx`). Keeping this React-free means importing it into a server module
 * never pulls React into the Nitro/SSR bundle.
 *
 * `code` is THE primitive code block — a single syntax-highlighted snippet,
 * Notion-style (one border, hover-revealed language switcher + copy, collapse to
 * N lines). It deliberately holds ONE snippet: a "file rail" of several files is
 * just the `tabs` primitive containing `code` blocks, so there is no bespoke
 * "code-tabs" container. The legacy `code-tabs` block stays renderable for stored
 * documents but is no longer authored.

 * (`code ?? ""`, optional fields undefined when absent) so a snippet missing an
