Home, on phones above all: every scroll animation follows your scroll position instead of a timer, and sections are as tall as their content.
Before, an animation started when its section crossed a line and then ran on a clock, so on a phone it often finished while the section was still below the screen. Now each step lights when it reaches the reading line and goes back if you scroll up. The 3D floor takes the page's colour and stops drawing when it is off screen.
