Lay out horizontal and vertical Japanese text with kinsoku, ruby,
emphasis, warichu, tate-chu-yoko and proportional font features.
Carry the layout through glyph paths, SVG export and text selection.
Update the Rust and ClojureScript binary formats together, including
the editor bridge and headless exporter. Resolve CJK fallback fonts
and add renderer tests and font fixtures.
When render-wasm is active, generate SVG for the Code inspector and
Copy as SVG from the WASM export path instead of classic SVG codegen.
Add multi-root render_shapes_svg so multi-select stays one document.
Closes#12567
When render-wasm is active, shape exports (single file, ZIP, and Export
boards multi-page PDF) run on the shared worker WASM module so the UI
stays responsive. A progressive PDF session (begin/add-page/finish)
updates progress per page; cancel settles on the client. The server
exporter path remains for the SVG renderer.
* ♻️ Move some constants out of app.render-wasm.api
- Moved to aapp.render-wasm.wasm where they can be imported
without pulling half the editor with them
- Renamed one for consistency
* 🔥 Delete unused function, update docstring
* 🎉 Copy v3 editor text with its styles in a payload
Copy and cut in the v3 text editor put the styled selection in a
hidden span of text/html. Add its codec and the clean-up for pasting
into another file or team.

* 🎉 Paste text copied in Penpot at the v3 editor caret
Text copied in Penpot keeps its styles when pasted at the caret. The
first paragraph keeps the target's attrs; later ones bring their own.
The context menu paste now shares the keyboard paste path.

* ♻️ Factor GL context initialization out of canvas init
- fixes setting of gl-context-handle to be after _init so an exception
does not leave invalid state behind.
- api.init-canvas-context uses a new webgl.init-context!
- this decouples config from init, so we can reuse it in benchmarks
- some helpers move to the webgl ns

* ♻️ Share structural batch upload through common helper
- Merge svg-filters and svg-fills to app.common.render-wasm.svg-derived
- Add serialize-shapes-batch! in common, shared by the sync and chunked
workspace paths
- Add a routing test for the helper and wires the svg-filters test.

* 🐛 Derive SVG effects inside single-shape serializer
- Single and batch paths: one svg effect derivation step
owned by shared serializers.
- set-object forwards the derived shape to its host attrs,
and the exporter reads the derived fills, so SVG-attr
fills, blur and shadow render as in the frontend.
- Adds regression test to the exporter.

* ⚡ Capture canvas snapshot only when the renderer is idle
* ⚡ Skip descendant silhouettes for frames with nested drop shadows
* 🔧 Add a profiling build mode for render-wasm
During reload-renderer!, reloading? keeps initialized?/ready? false
while set-objects runs (especially the sync path for small files).
Text content used that guard and was skipped; geometry already used
live?. Gate use-shape, has-shape, and set-shape-text-content on
wasm/live? so text is restored with the rest of the shapes.
Emit clipped `<image href>` for fills with a registered media URL instead
of Skia base64 embeds. Register URLs from the frontend and exporter via
store_image_url. Cover rect, path, frame, and text (glyph clip) cases in
SVG export tests.
Closes#11383
* 🐛 Align WASM auto-width text size with HTML measurement
Include the HTML paragraph-set 1px right margin in Skia auto-width
so WASM and DOM measurements match.
* ⚡ Scope and defer post-font WASM text relayout
Track pending font faces per shape, force-relayout only affected
texts, defer stale-selrect sync until the first tiles paint, and
batch request-render after attr updates. Tolerate missing font-face
keys so callers that omit them do not blow up.
Upload structural shape attrs (base, children, blur, shadows,
flex, layout-item) via multi-shape `_set_shapes_batch` FFI in
chunks of 512, then apply host attrs with use-shape selection.
Present visible tiles via ViewportReady so zoom settle turns sharp
without waiting on the interest ring, and paint at atlas slot size so
DPR 2 does not rasterize 1024 only to downscale into 512 slots.
Pan/zoom via render_from_cache while the tile atlas is still empty
left a blank workspace under the page-transition blur. Ignore
set-view-box / view-interaction-start until tiles-complete, block
pointer events on the viewport SVG, and flush any deferred local
viewport sync when the overlay ends.
HQ tiles are 512px and the atlas stays at 4096² (64 full-size
slots). Browser zoom plus a forced ?dpr= can need more visible
tiles than that, and a framebuffer larger than the GPU allows.
Pack interest tiles into smaller atlas cells, blit at 512 then
scale, and inset Linear samples so seams do not bleed. Clamp the
canvas backing store and DPR together, wrap Skia at the real
drawingBuffer size, and wait one frame after DPR changes so CSS
client size and overlays stay aligned.

Pass performance.now from finalize/debounce and re-anchor the WASM
budget if the stamp is 0 or already past max_blocking_time, so HQ
tiles are not yielded after a few nodes with almost no real work.
Every pointerup unconditionally fires finish-panning and finish-zooming,
which call finalize-view-interaction!. This triggered internal-render
(and reset_canvas) on plain clicks — causing a visible white flash on
large viewports or weak GPUs.
Add a guard so finalize-view-interaction! only runs when a view
interaction (pan/zoom) is actually active.
Fixes#10915

* 🐛 Prevent WASM panics during WebGL context restore
Delay context-restored until reload finishes and no-op app
mutations while reloading so resize/modifiers cannot panic
mid-teardown.
* 🐛 Fall back to CLJS bool content when WASM is not ready
Returning nil from calculate-bool would persist empty path content
during context loss/reload; use path/calc-bool-content instead.

* ✨ Add LRU eviction to the wasm image store
* ✨ Add RasterFormat to encode png, jpeg and webp from wasm

Position-data entries for text shapes could omit the :fills key when the
element had no explicit fills, causing backend malli validation failures.
- Use get-default-text-attrs as base in WASM calculate-position-data
- Default fills when CSS --fills property is absent in DOM calc path
