Export correctness:
- Honor the user's color-range (Limited/Full) on the software encode path:
thread full_range through gpu_yuv (new shader range uniform), the CPU
swscale fallback (sws_setColorspaceDetails → BT.709 + range, fixing the
BT.601 hue/level shift on odd-width exports), and the encoder color tags.
- Reject HDR + WebM up front with a clear message and log the forced HEVC
override instead of producing an unplayable file.
- Delete dead render_frame_to_rgba_hdr (hardcoded Stretch; live HDR path
already honors the fit mode).
Decode/playback (video.rs):
- Drain the decoder at EOF (send_eof + flush) so the final B-frame-delayed
frames render instead of erroring; per-frame logic extracted to a helper.
- Missing-PTS frames continue monotonically rather than snapping to ts=0.
- Force exact thumbnail width so sub-128px sources aren't shown stretched.
Resource leaks (gpu-video-encoder):
- dmabuf import_raw: RAII guard frees the duped fd + partial VkImages/memory
on every error path.
- vaapi alloc: free device/frames-ctx/AVFrames on the unexpected-DRM path.
Data model / robustness:
- collapse_boundary_spikes requires a full curve reversal (all control
points) so it no longer deletes a real lens/sliver and drops the fill.
- Export audio spin-wait ignores a stale `finished` flag when a forward
seek is pending (was rendering silence over real audio).
- RasterDiff apply_before/after take current dims and skip on a post-resize
mismatch.
- beam_archive read_media_full caps the preallocation from untrusted total_len.
UI/visual:
- SVG export skips hidden layers/empty groups; import folds fill-opacity into
gradients and surfaces failures as a notification.
- Active raster-layer border uses playback_time + overlay_transform.
- gpu_brush remove_layer_texture also evicts the stale low-res proxy.
- ensure_raster_resident_for_undo registers faulted frames in the LRU so
resident RAM stays bounded.

Export (lightningbeam-core/svg_export.rs): document_to_svg walks vector
layers/groups at a given frame and emits <path> per fill (solid or
gradient via <defs>) and per stroked edge. Wired into the export dialog
as an "SVG" tab; written synchronously. Raster/video/effect layers are
skipped (vector-only, lossless), structured for a later rasterize pass.
Import (lightningbeam-editor/svg_import.rs): import_svg parses via usvg,
bakes each path's absolute transform into geometry, converts segments to
cubic edges, and maps solid/linear/radial paint to ShapeColor/
ShapeGradient. .svg is detected in the Ctrl+I Import handler and added as
a new vector layer (keyframe at the playhead). file_types gains
FileType::Vector + VECTOR_EXTENSIONS.
Tests: svg_export::export_tests (core) and svg_import::tests (editor).
