Feature Request: Improve visual accessibility for users with low vision

Reference: #4180

I’d like to suggest a few improvements to enhance visual accessibility in Multipass, especially for users with low vision:

Support for high contrast themes and light/dark mode in any graphical or terminal-based UI.

Scalable fonts and better compatibility with screen magnifiers.

Avoid using color as the only indicator for status or important information — adding icons, symbols, or text labels can make the interface clearer for everyone.

Read the referenced issue #4180 first, then locate the graphical and terminal-based UI entry points involved in Multipass. Define the supported accessibility scope before implementation; done should include high-contrast and light/dark support, scalable text and screen-magnifier compatibility, and non-color status indicators.
