Replace the split snapshot/native renderer paths with a single composition pipeline (compositionRenderer.ts) that: - Loads actual source images and uses naturalWidth/Height for correct full-resolution sampling (fixes top-left-corner-only bug caused by data.w/h being capped to 600px display dimensions) - Routes image-only selections through native Canvas 2D composition - Falls back to viewport snapshot for mixed/unsupported selections with explicit warnings instead of silent degradation - Resolves group children via itemResolver for proper group export - Rejects group children from native composition (local coords incompatible with world-space drawing) - Adds canvas size safety limits with auto-downscale - Guards VideoSprite._drawFrame against null texture source race condition during zoom-triggered culling New files: - compositionRenderer.ts — unified composition module - compositionRenderer.test.ts — 16 tests for entry flattening, bounds, dimensions, group handling Modified: - clipboard.ts — uses composeSelection() instead of direct renderers - export.ts — uses composeSelection() + getCompositionDimensions() - Editor.tsx, useShortcutHandler.ts — pass scene for group resolution - VideoSprite.ts — null guard on texture source in frame loop
