The Blur background toggle becomes a 0-100% slider. The amount picks the dual-Kawase pyramid depth and tap spread in one shared helper (background_blur_steps), read by the D3D11, Metal and wgpu backends. 50% is exactly the old switch; projects, presets and scenes that stored the switch read true as 50% and false as 0.

In @src/lib/ai-edition/document/migrate.ts:
- Line 321: In the reverse-migration flow, update the `backgroundBlur`
assignment so `Object.assign` copies the legacy fields before
`editor.backgroundBlur` is set from `readBackgroundBlur(legacy, 0)`. This
preserves blur enabled by `legacyEditor.showBlur` when `backgroundBlur` is
absent, including in the returned project and subsequent export.
In @src/lib/ai-edition/stylePresets.ts:
- Line 416: Update lookFromLegacyEditor to convert a boolean legacy showBlur
value into backgroundBlur before filtering through LOOK_LEGACY_EDITOR_KEYS; only
derive it when backgroundBlur is undefined so an existing backgroundBlur value
is preserved.

Summary
Blur background becomes a 0–100 % slider instead of an on/off switch.
background_blur_steps(frame_geometry.rs), maps the amount to pyramid depth and tap spread. D3D11, Metal and wgpu all read it, so the three backends blur alike.showBlur: boolean→backgroundBlur: number(0..1, inSETTING_BOUNDS).trueas 50 % andfalseas 0.backgroundBluris now numeric.Tests
tsc(app + tests), Biome on changed files.cargo test -p openscreen-compositor --lib: 374 passed (Windows), newbackground_blur_stepstest checks off at 0, old look at 0.5 and a monotonic radius.🤖 Generated with Claude Code
