A3S Office 0.53.0

Highlights

• Extend Writer text boxes with five bounded shape presets: rectangle, rounded rectangle, ellipse, diamond, and triangle. The typed shape state drives the contextual ribbon, live page, preview, PDF capture, Undo/Redo, and native DOCX geometry.
• Import isolated WPS mc:AlternateContent text-bearing wps:wsp drawings while preserving geometry, fill, outline, padding, vertical anchor, floating placement, text, and stable drawing-property identity.
• Keep mixed paragraphs, VML-only connectors, arbitrary or unsupported shapes, malformed bodies, and unsupported DrawingML branches as explicit compatibility diagnostics.
• Fix the structured-document model boundary so imported data-text-box-* attributes survive parsing instead of resetting to defaults.
• Publish bilingual frozen 0.53.0 documentation, a Windows WPS COM shape probe, deterministic WPS fixtures, and responsive desktop/compact UI evidence.
