Loading animation

[Kenny477]

Task: Design and implement a new loading animation.

Objectives:

• Loading animation fits color theme (white/blue in light mode and black/blue in dark mode)
• Loading animation allows correct theme to be computed before actual landing page render
• Loading animation is creative and fits overall design (currently thinking about porcelain themed animation with blue cracks forming across white/black screen)
• Loading animation completes quickly for users to get to the page
