[Bug]: Global menu text can become black and fuzzy after foreground updates

[kkkzbh]

I have:

• Searched if this issue hasn't been reported yet.
• Verified that I am using the latest version (see Widget settings > About page or top right corner for version 1.1.0 and later), should be the same as https://github.com/luisbocanegra/plasma-panel-colorizer/releases/latest

Install method used:

• Using Plasma's "Add new widget" (KDE Store)
• AUR
• Nix package
• Manually from the latest source code

Describe the bug

With a transparent panel and foreground color/shadow customization enabled, global menu labels can intermittently become thick black/fuzzy text instead of using the configured foreground color and shadow.

From investigation, foreground color application updates the Kirigami theme only on direct text/icon targets. Some dynamically-created/global-menu item trees keep their text styling on container items, so child labels can continue inheriting an old/dark text color.

Steps to reproduce

1. Use Panel Colorizer v7.2.0 on Plasma 6 Wayland.
2. Configure a transparent panel.
3. Enable foreground text/icon color customization and foreground shadow for panel widgets.
4. Add a global menu widget to the panel.
5. Trigger panel item updates, for example by reloading Plasma or changing visible panel widgets.
6. Observe the global menu text after the foreground update.

Observed Result

The global menu can render as heavy black/fuzzy text. The foreground state appears to be applied inconsistently when the menu item tree contains non-text container nodes.

Expected Result

The global menu should keep the configured foreground color and shadow.
