- New mobile/inspector.rs: when something is selected/focused, a bottom sheet
overlays the lower stack (no reflow) above the transport, showing the object's
properties by reusing InfopanelPane full-bleed. Header shows a title + ✕ to
deselect; jump-to chips (Timeline, Nodes) reframe the stack to that surface
with the selection kept. Grab handle resizes the sheet.
- Make the Infopanel Layer section editable (benefits desktop too): Name (text,
commit on Enter/blur), Opacity and Volume sliders (live preview, single-undo
on release), and Mute/Solo/Lock toggles. Backs the plan to reduce mobile layer
headers to a minimal swatch.

Introduce editable text layers: a resizable text box with editable text,
font size, color, font family, and alignment.
Core:
- New TextLayer/TextContent (text_layer.rs), wired into AnyLayer/LayerType
and all the exhaustive match sites; structured so content can be keyframed
later via content_at().
- fonts.rs: thread-local parley FontContext with three bundled fonts
(Liberation Sans/Serif/Mono, SIL OFL), system-font enumeration consolidated
to base families, document-embedded fonts, glyph/caret/selection geometry,
and a background preloader for the picker fonts.
- Rendering via parley layout + Scene::draw_glyphs (renderer.rs); text
composites through the vector path.
- Actions: CreateTextClipAction (vector-layer branch, undoable),
SetTextContentAction, ResizeTextBoxAction.
- .beam font embedding: MediaKind::Font rows (content-hash dedupe) written on
save and registered on load, with bundled-default fallback.
- VectorClip content bounds include text boxes so text-only clips are
selectable/draggable.
Editor:
- Text tool: click empty/raster/video to create a top-level text layer, or a
vector layer to create+enter a clip containing the text; click an existing
box to edit it.
- Hybrid in-place editing: a hidden egui TextEdit drives input/IME/caret while
the text and caret/selection render in Vello; empty just-created layers are
removed on commit.
- Selection outline + 8 resize handles (re-wrap text) with hover cursors;
factored the corner/edge resize-cursor mapping shared with the Transform tool.
- Info panel: edit text, size, color, alignment, box size, and a font-family
picker that previews each entry in its own font (fonts preloaded in the
background to avoid hitches).
Deps: add parley (git, pinned to match vello's peniko); bundle Liberation
fonts under lightningbeam-core/assets/fonts. Gitignore the local
.cargo/config.toml used to select a machine's ffmpeg.
Resizing the document leaves raster layers as-is (canvas keeps its old pixel size,
anchored top-left). To reconcile, the info panel now shows the active raster
layer's canvas size — driven by the *active* layer, not selection focus, since
painting doesn't focus the layer — and, when it differs from the document, a
Scale / Expand-Crop toggle + a "Layer to document size" button.
- RasterKeyframe::resize_to(w, h, mode): always applies the new declared size;
resamples (Lanczos3) when Scale, top-left pad/trim when Canvas, and only touches
the buffer when pixels are resident (a blank canvas just takes the new size).
Sets texture_dirty so the stage's dirty-scan refreshes the GPU texture.
- ResizeRasterLayerAction resizes every keyframe with undo, holding a (read-only)
RasterStore so paged-out keyframes are loaded one at a time rather than bulk.
Resized keyframes stay resident + dirty and persist on the next full save (no
incremental store write to page them back out). Scale is lossy/compounds;
Expand-Crop is lossless.
Add a per-document HDR→SDR mapping applied at the final linear→sRGB encode, so
super-white (HDR) video highlights can be recovered instead of hard-clipped:
- core: HdrOutputMode {Clip (default), HighlightRolloff} on Document (serde
default), with a SetDocumentPropertiesAction variant for undoable edits.
- shaders: a fs_main_rolloff entry point (preview linear_to_srgb.wgsl + the export
inline shader) applying a C1 highlight knee — identity below 0.8, smooth rolloff
[0.8,∞)→[0.8,1). SDR below the knee is untouched; Clip stays the historical path.
- preview (stage.rs) and both export encodes (video_exporter.rs) pick the pipeline
variant from document.hdr_output_mode — one value per frame, so no per-pixel
uniform; mirrors the existing fs_main_straight pattern.
- UI: an "HDR output" dropdown in the Document section of the info panel.
Default (Clip) is bit-identical to previous behaviour. Completes Stage A:
HDR-correct input (pt 1) + SDR-safe output mapping. HDR export (10-bit P010/PQ)
and HDR display remain Stages B/C.
Resolve all compiler warnings across daw-backend, lightningbeam-core, and
lightningbeam-editor:
- Delete dead code: the superseded CPU raster tools in raster_tool.rs
(EffectBrush/Smudge/Gradient/Transform/Warp/Liquify/Selection — replaced by
the GPU path), plus orphaned helpers and never-read struct fields.
- Mechanical fixes: drop unused imports/variables/mut, underscore unused params,
`drop(&x)` -> `let _ = x`, deprecated egui::Rounding -> CornerRadius, snake_case
rename, elided-lifetime Cow<'_, [u8]>.
- Keep the WIP CSS theming system (theme.rs/theme_render.rs) under
#[allow(dead_code)] rather than deleting it.
Editor checks warning-free; 293 core tests pass.
Image fill is now a tab in the Fill type row rather than a separate dropdown. When
Image is active, an asset-picker combo selects which image; switching to None/Solid/
Gradient clears the image fill (it otherwise overrides them). The Image tab only
appears when there are imported image assets.
- SetImageFillAction (core): set/clear `image_fill` on the selected VectorGraph fills,
with per-fill undo (mirrors SetFillPaintAction). Image takes render priority; clearing
reveals the colour/gradient underneath.
- Info Panel Shape section: an "Image:" combo listing the document's image assets (+ None)
for the selected fill(s), showing the current assignment. Assign/clear pushes the action.
This lets an existing shape be given (or cleared of) an image fill, complementing the
import/drop placement. Next: 3.5b — persist image assets in the .beam container.
The standalone egui window didn't fit the UI. Replaced it with a collapsible
"Onion Skin" section at the bottom of the Info Panel (Enabled checkbox + frames
before/after + opacity), available regardless of selection. SharedPaneState carries
a mutable `onion_skin` ref for the controls (distinct from the gated `onion` copy
used by rendering).
