What changed

  • Restored primary, pressed, disabled, and on-accent palette bindings for Liquid Glass Button and RaisedButton UIIDs in light and dark appearances while preserving the new glass surfaces.
  • Regenerated the shipped iOS Modern theme resources.
  • Made PaletteOverrideThemeScreenshotTest reinstall its overrides after capture retries and the HTML5 Material-to-iOS theme switch.
  • Added runtime screenshot assertions and expanded the native-theme binding unit coverage.

Why

PR #5274 replaced several palette-backed Liquid Glass colors with hard-coded fidelity colors. This broke application accent overrides: the palette screenshot's Raised/Text/Disabled controls rendered with default blue/black/grey instead of magenta/teal. The screenshot test could also silently lose its override after a retry or theme reload and accept those default colors as new goldens.

This restores the established theming contract without removing the Liquid Glass geometry, borders, blur, or materials.

Validation

  • Java 8 targeted core test: NativeThemeBindingsTest (2 tests passed)
  • Screenshot app compilation and Codename One bytecode-compliance check
  • git diff --check

The currently committed blue palette screenshots are expected to be flagged by the next platform screenshot runs and replaced from their real device renders.
