Tool output tables have poor readability - low contrast text

[tfsq]

Problem

Tool outputs that render tables have very low contrast text, making them difficult to read.

Example

The table shows:

• Light gray text on white background
• Column headers barely visible
• Data values (table names, column names) are hard to distinguish

Impact

• Strains eyes when reviewing query results or metadata
• Slows down analysis workflows
• Accessibility concern for users with visual impairments

Suggested Fix

• Increase text contrast (darker gray or black text)
• Add subtle row striping or borders for better visual separation
• Consider respecting system dark/light mode preferences

Context

This appears in tool outputs like queryexpert__find_table_meta_data when displaying table metadata results.
