Steps to replicate the issue (include links if applicable):

• In dark mode theme, navigate to articles that contain image captions or expandable tables with subtitles.

Example: https://en.wikipedia.org/wiki/Arab_Liberation_Army?wprov=sfla1

What happens?:
Text in image captions and certain subtitles within expandable tables appears with very low contrast, making it difficult to read in dark modes.

The contrast issue is especially noticeable with gray or dimmed font colors used in dark backgrounds.

What should have happened instead?:
Text should maintain sufficient contrast against the dark background to ensure readability and accessibility in dark modes.
