### Issue Subcategory:
Focus indicator has low contrast

### User Experience:
People who are primarily using keyboard to navigate and have low vision may not be able to see where focus is located, making keyboard navigation hard to follow.

### Repro Steps:
Open URL: http://localhost:5021 > Home and Privacy links> Observe the issue.

### Actual Result:
When keyboard focus moves to the Home and Privacy links, the focus border is visible but has a contrast ratio of only 1.285:1, making it difficult to perceive.

### Expected Result:
The focus indicator should have a contrast ratio of at least 3:1 against adjacent colors/background so that keyboard users can easily identify the focused element.

### How to Fix:
Adjust the focus indicator color to achieve 3:1 contrast. Consider using a thick (2px+) outline with a contrasting color, or combine outline with `box-shadow` for visibility on varied backgrounds.
