[Feature]: Add Dark Mode Toggle to the Website

[DelacroixAD]

What problem does this solve?

The website currently supports only light mode. Adding a dark mode toggle would improve user experience, accessibility, and overall UI appearance, especially for users browsing at night or for long durations.

Proposed solution

Add a dark/light mode toggle button
Store user preference using localStorage
Apply dark theme across all pages/components
Ensure smooth transition between themes
Maintain responsive design in both modes

Which part of the app does this affect?

Homepage and form

Estimated complexity

Medium (one function and one template change)
