* refactor: rename @open-pencil/codegen to @open-pencil/emit
In design tools codegen means design-to-code, which is dom-css's job and
Core's codegen tools'. The package builds and prints the syntax trees
exporters emit, so name it for that. It has not been released yet.
* fix: alias @open-pencil/emit to its source in Vite
The rename missed the escaped regex, so Vite resolved the package through
its built dist output.
* refactor(codegen): share syntax-tree code generation between exporters
dom-css printed Tailwind JSX with its own esrap JSX builders and kept TypeScript template helpers under its Storybook export. The OpenPencil JSX exporter needs the same JSX builders, and design-jsx and dom-css may not depend on each other.
@open-pencil/codegen holds both: es for ESTree templates and modules (moved from dom-css) and jsx for JSX elements, attributes, text, and printing, including the literal rules that keep exported strings from being reinterpreted. dom-css no longer depends on acorn and esrap directly.
* refactor(design-jsx): print JSX export as syntax trees
sceneNodeToJSX concatenated strings with hand-written escaping and indentation. It now collects typed props (moved to export/props.ts) and prints them with @open-pencil/codegen's JSX builders. Output is unchanged except for text: special characters print as a string expression instead of entities, and multi-line text keeps its line breaks, which the old line-splitting lost on render.
* docs(codegen): fix package metadata and dependency rules
codegen's repository.directory still named design-jsx, the README mentioned es without showing it, and the design-jsx and dom-css guides still said they depend only on scene-graph.
* test(core): move the JSX export round-trips to the design-jsx test home
Covers tabs in layer names and text, which JSX keeps as written.
* refactor(design-jsx): extract design JSX into its own package
Design JSX elements, helpers, schema, reference, and JSX export only need
the scene graph, yet lived in Core, so every consumer of the authoring API
pulled in the renderer, layout, and file formats.
@open-pencil/design-jsx now owns them and depends only on scene-graph. The
renderer takes icon lookup, SVG conversion, vector creation, and layout as
DesignJSXServices; Core binds its own and exports the bound renderJSX and
renderTree from @open-pencil/core/design-jsx.
* feat(design-jsx): export the JSX runtime for TSX authoring
The package already had a JSX runtime, but nothing exported it, so design
trees could only be written as function calls or JSX strings. Export
`./jsx-runtime` and `./jsx-dev-runtime` so `jsxImportSource` works, and make
`Fragment` produce the same empty-type node as `<>` in `renderJSX` strings.
* fix(design-jsx): render fragments nested in other elements
A fragment builds a node with an empty type, which only renderJSX expanded, and only at the root. Nested fragments and fragments passed to renderTree failed with 'Unknown element: <>'. Inline fragment children when trees are built, and share root expansion between renderTree and renderJSX.
