Greptile Summary

This PR fixes invisible text in the Catppuccin Latte (light) theme by replacing the black color in [colors.light.normal] with a more contrasting value. The previous Mantle color (#e6e9ef) was too close in luminosity to the Base background (#eff1f5), making any text rendered with ANSI color 0 nearly invisible.

• Fix: Changes [colors.light.normal] black from #e6e9ef (Mantle) to #ccd0da (Surface 0), a legitimate step darker in the Catppuccin Latte palette, restoring legible contrast.
• Scope: Change is confined to one value in themes/catppuccin.toml with no side effects on the dark (Frappe) theme or the bright-color section of the light theme.

Confidence Score: 5/5

Safe to merge — this is a one-value color correction in a theme file with no logic or runtime impact.

The change is a straightforward swap of one hex color for a slightly darker one from the same palette. The before/after screenshots in the PR description confirm the fix works as intended, and the value #ccd0da (Surface 0) is the canonical Catppuccin Latte color appropriate for this slot.

No files require special attention.
