Made the page look a lot more space-y with a dark gradient theme and a starfield background. Allowed the user to switch the date to a previous one and the corresponding image of that day. Added shooting stars that streak by on their own and move from your cursor when you click the background.

Bugs I fixed:

• Shooting stars flew backward (gradient was on the wrong end)
• Stars spawned offset from the cursor (was positioning by the corner)
• All shooting stars appeared at once after leaving the tab (paused the spawner with the Page Visibility API)
