PNG export omits TEXT nodes (blank where text should render)

Summary

When rasterizing a frame to PNG with openpencil export, TEXT nodes are omitted — every glyph is missing from the output, while all other content (shapes, fills, gradients, strokes, positions, layout) renders correctly.

Environment

• @open-pencil/cli 0.14.0
• macOS (Darwin)
• Source document: a .fig (Figma "Save Local Copy" export)

Command

openpencil export document.fig --node <FRAME_ID> --scale 2 -f png -o out.png

Observed

In the resulting PNG, the frame's rectangles, ellipses, gradients and strokes are all rendered at the correct positions and sizes — but no text is drawn. For example:

• a circular badge that contains a short text label exports as an empty circle
• a rounded "pill" containing a caption exports as an empty rounded rectangle
• button labels are blank

Expected

Text nodes rendered as glyphs, matching the design.

Notes

• Text is also missing at --scale 1, so it is not a scaling issue.
• Non-text vector content is faithful, so geometry/paint work — it appears specific to the text rasterization path.
• I have not yet confirmed whether -f svg preserves <text>; happy to test if useful.
• Fonts referenced by the document are standard system / common Japanese faces; a missing-font fallback would still be expected to draw something, but the glyphs are entirely absent.
