Move the 30 flat modules under src/scene/ into six folders by role: convert (entity→geometry), text (fonts/shaping), model (render models), pick (hit-test/selection/grips/xclip), view (camera/transform/render), cache (block + property caches). pipeline/ is unchanged. Full path migration — all `scene::X` references become `scene::<group>::X`, no compatibility re-exports. render.rs items that were `pub(super)` (parent was scene) become `pub(in crate::scene)` to keep their original scene-wide visibility. No behavior change; build and tests are green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

//! Unified GPU shader widget for both model and paper layouts.

//!
|
|
//! There is one `shader::Program` for the whole canvas. `Scene::build_viewports`
|
|
//! decides what to render — model layout produces one viewport per tile
|
|
//! (`active_viewports` iterates `model_tiles`), paper layout produces one per
|
|
//! content viewport entity. Each one is drawn into its own scissor rect by a
|
|
//! dedicated inner `Pipeline` (kept in the `MultiPipeline` outer).
