Dark mode borders: too much contrast?

[nhirschey]

In dark mode, should the line border dividers be made darker to reduce contrast?

Specifically, in light mode the vertical line to the left of the section outline (left of "License", "Release Notes", "Source Repository") are low contrast. I like the low-contrast light-mode style.

In dark mode however the lines are very high contrast, which feels too busy. Especially the double white vertical lines on the right "on this page" outline. I prefer a subtler vertical line like we have in the light-mode style.
