- ui-egui/softpaint: pure-Rust rasterizer for tessellated egui output (gamma-space premultiplied
blending like egui-wgpu, bilinear texel-centre sampling, scissor clips, tie-break rule so shared
edges blend once, parallel row bands, deterministic) + CPU texture mirror from TexturesDelta.
- ui-egui/headless: HeadlessView (offscreen context with our fonts/theme) and Headless (windowless
app session: logic+ui per frame, answers viewport Screenshot/InnerSize/Close, settle loop,
control requests through the shared handler).
- ui.screenshot {headless: true} in the running app renders from the logic tick (works while the
window is occluded / display asleep); windowed captures fall back to headless after 2 s.
Screenshots now wait for in-flight renders, not just queued ones.
- lightcraft-cli snapshot [--demo|--library DIR] [--script f.jsonl] -o out.png --size WxH --scale S.
- Fixes found with it: dialog backdrop was painted over the dialog itself (now an area below the
window); dialog content padding; crop overlay options use our buttons (registered widget ids).
- Docs: control-protocol.md (headless section), AGENTS.md (prefer headless when unattended).
