Fix

Observe Reduce Transparency changes in ProgressiveBlurView using a weak observer and release it during teardown. Reuse the fallback update without rebuilding the variable-blur filter. Clear the opaque background and clipping when LiquidGlassContainerView returns from its fallback.

Compatibility / breaking changes

No API changes. Mounted views now follow the accessibility preference immediately, and disabling it restores the configured glass appearance.

Verification

Compiled actual Swift classes with the Simulator SDK and executed them against UIKit using an injected preference/notification source: both baseline failures (progressive update and glass restoration) pass after the fix. No device accessibility setting was changed.

Combined review branch: 40 existing Jest tests across four suites, TypeScript, ESLint (three pre-existing inline-style warnings), Bob builds, web-entry graph validation and whitespace checks passed. No checked-in tests/specs were added or changed. Consumer integration passed both products’ Android Debug and iOS Simulator Debug builds, four production Metro bundles, 13 web targets and four browser-extension targets. The upstream example built for Android and iOS, exported for web, and its iOS home screen was launched and visually inspected. Physical-device, signed-release and Android runtime testing were not performed.

Closes #135

Summary by CodeRabbit

  • Accessibility

    • Liquid Glass and Progressive Blur views now respond immediately when Reduce Transparency is enabled or disabled.
    • Progressive Blur applies the configured fallback color while Reduce Transparency is enabled, including while mounted, without changing view content.
    • Configured glass and blur effects are restored when the setting is turned off on supported iOS 26+ configurations.
  • Documentation

    • Clarified dynamic Reduce Transparency behavior, supported iOS requirements, and restoration while views remain mounted.

📝 Walkthrough

Walkthrough

The iOS views now respond to Reduce Transparency changes. Progressive blur updates its fallback dynamically. Liquid glass clears fallback styling when native glass returns. Documentation describes the mounted transitions.

Changes

Accessibility transition handling

Layer / File(s) Summary
Progressive blur fallback updates
ios/Views/ProgressiveBlurView.swift, website/src/content/docs/progressive-blur-view.mdx
ProgressiveBlurView observes Reduce Transparency notifications, updates its fallback during setup and blur changes, removes the observer during deinitialization, and documents the iOS behavior. The Android documentation describes the custom gradient masking implementation.
Liquid glass fallback reset
ios/Views/LiquidGlassContainerView.swift, website/src/content/docs/liquid-glass-view.mdx
When iOS 26 native UIGlassEffect is available and Reduce Transparency is disabled, the native glass path clears the solid background and corner masking. The documentation records this mounted transition.

Explanation

The iOS implementation and the related iOS documentation changes are in scope for issue #135. The Progressive Blur documentation also changes an Android statement from “wraps” to “extends” the QmBlurView BlurView. Issue #135 contains no Android requirement, so this wording change is unrelated to the linked issue.

- Line 22: Qualify the statement about disabling “Reduce Transparency” restoring
the configured glass effect so it applies only to the native iOS 26+
UIGlassEffect path. Avoid implying that older iOS versions or the older-compiler
branch restore UIGlassEffect, since LiquidGlassContainerView.updateFallback()
restores UIVisualEffect blur there.

Qualified the documentation as suggested: the restored configured glass effect is now explicitly limited to iOS 26+ when native UIGlassEffect is available.
