- init_headless + RenderState::try_new_headless / Surfaces::try_new_headless:
boot on CPU-raster placeholders, no GL context
- render_shape_raster + render/raster.rs: CPU raster PNG export
- CanvasCtx: GPU-free context shared by the PDF and raster canvas paths
- get_fonts_for_shape + Shape/TextContent font enumeration
- clear_fonts; ImageStore::without_gpu
- _build_env: ENVIRONMENT=web,node so the module loads under Node
