Text unreadable in high contrast mode on Windows

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have custom nodes enabled

### What happened?

When Windows high contrast theme is enabled, the ComfyUI frontend text blends completely with the background, making it impossible to read. The issue is visible in the attached screenshot, where UI elements like "Unsaved Workflow", "图形", "管理扩展功能", and "任务队列" have insufficient contrast against the light background, rendering the interface unusable.

### Steps to Reproduce

### Additional Context

No source file or test is named. First reproduce the problem in Edge on Windows with a high-contrast theme and inspect the frontend styles controlling the affected text and backgrounds. Done means the listed UI elements remain readable with sufficient contrast and the existing interface still works.
