[Docs][Accessibility]: v4 docs OAuth diagram poor visibility #13295
Description
What is the improvement or update you wish to see?
The v4 docs page on OAuth providers renders a diagram of an OAuth workflow with poor color contrast in dark mode. Update the colors of the affected text to meet minimum AA standards for accessible text.
Is there any context that might help us understand?
The v4 docs page renders a SVG diagram of an OAuth workflow. The SVG text elements do not update their color to suit the users selected theme (dark mode/light mode). Instead these elements render text with color #333 on a black background, resulting in a color contrast ratio of 1.66:1. The minimum ratio for color contrast for text is 4.5:1 with some exceptions (See WCAG Success Criterio 1.4.3). Observed 10/21/25 via Google Chrome Version 140.0.7339.133
