feat(design-jsx): export every property the renderer accepts (#814)
* feat(design-jsx): export every property the renderer accepts

JSX export wrote only part of a layer: one solid fill, one stroke
without its alignment, shadows as repeated attributes, background blurs
as layer blurs, and nothing for hidden children, constraints, size
limits, absolute positioning, vertical text alignment, masks, or
variable bindings. Rendering an export lost those properties, and JSX
diffs could not see changes to them.

The export now writes them, using paint and effect helper calls when a
shorthand cannot express a value exactly, and leaves out values the
renderer would infer, so ordinary output stays as it was. Prop values
can now hold objects, arrays, and helper calls, printed through
@open-pencil/codegen's builders, which gain a call expression. The
language gains `visible`, `locked`, `constraints` (Figma's constraints
object with lowercase values, as `blendMode` uses), `italic`,
`strokes`, `strokeWeights`, `strokeCap`, and `strokeJoin`, and now
applies `strokeAlign`, `strokeDash`, and the size limits, which it
accepted but ignored. Per-corner radii are written even when the
uniform radius is 0. A round-trip test renders each case's export and
checks the fields and that exporting again changes nothing.

* docs(fig): name the saved-glyph fixture by its repository path

The observation note linked the fixture with a relative path climbing four directories. Other notes name fixtures by their repository path, which reads the same from anywhere.

* fix(design-jsx): export the node-level dash pattern

A node's own dashPattern was not written, so a node dashed at node level
came back solid and the DOM/CSS export chose a solid border. It now
round-trips as a separate dashPattern prop; strokeDash stays the
stroke-local dash.

@open-pencil/fig

.fig file-format package for OpenPencil.

The package owns the outer .fig archive boundary and is the staged home for Figma-specific SceneGraph conversion policy. Production SceneGraph read/write remains available through @open-pencil/core/io while conversion modules move behind this package's public API.

Current ownership:

  • Complete .fig archive parsing through parseFigBuffer()
  • .fig archive assembly through writeFigArchive()
  • Canvas payload and image resource handling
  • readFigContainer() / writeFigContainer() helpers for raw fig-kiwi payloads
  • .fig source and archive result types
  • NodeChange-to-SceneGraph property conversion, including styles, plugin metadata, text, paint, vector, and font policy, through @open-pencil/fig/node-change
  • Component-property, symbol-override, derived-symbol-data, and instance synchronization policy through @open-pencil/fig/instance-overrides
  • Effective raw-metadata precedence and invalidation over SceneGraph's format-neutral edited-field tracking
  • SceneGraph-to-NodeChange export conversion with an explicit glyph-outline runtime service
  • Package-local archive, conversion, instance, export, and dist smoke tests

Architecture documentation

Start with the package docs for the source model, instance evaluation, materialization, document sessions, export, and validation contracts.

Planned ownership:

  • Oracle-backed .fig fixtures

Non-goals:

  • Generic Kiwi schema/runtime internals — use @open-pencil/kiwi
  • Format-neutral IO registration, export targeting, CanvasKit thumbnails, or browser workers — use @open-pencil/core/io
  • Editor actions, renderer behavior, Vue/app UI, CLI formatting, or MCP transport

This follows the existing @open-pencil/pen pattern: a format package owns its source model/parser and SceneGraph policy, while core registers it in the shared IO system.
