[kodjima33]

Summary

• White text + white background made buttons invisible in dark mode on the Memories page
• "Add Your First Memory" and "Retry" buttons were completely hidden
• Fixed by using purple background with white text (matches other CTAs in the app)

Test plan

• Open Memories page with no memories — "Add Your First Memory" button should be visible (purple)
• Trigger error state — "Retry" button should be visible (purple)

Greptile Summary

This PR fixes a UI bug where the "Add Your First Memory" and "Retry" buttons on the Memories page were invisible in dark mode due to white text on a white background. The fix changes both buttons to use OmiColors.purplePrimary (#8B5CF6) as the background with white foreground text, matching the app's established CTA button style. The border overlay is also removed as it is no longer needed with the solid-colour background.

Changes:

• Both buttons' backgrounds changed from Color.white to OmiColors.purplePrimary
• Both buttons' foreground color changed from OmiColors.textPrimary to .white
• Removed RoundedRectangle border overlay from both buttons (cleanup)
• Styling is now consistent with other primary CTAs in the desktop app (e.g., OnboardingChatView, FileIndexingView)

Confidence Score: 5/5

Safe to merge — focused bug fix with no logic changes, only corrects button visibility styling.

The change is minimal (8 lines removed, 2 changed), directly addresses the described bug, and aligns with the established CTA style already used across the desktop app. No logic, data flow, or API contracts are affected. No new issues introduced.

No files require special attention.
