Initial low vision features added. xzoom needs to be installed for magnification. This first implementation is probably terrible, feedback welcome for improvement. Screen lock can now happen when I38 starts. As a reminder, it's not as secure as one of the system lockers, but it is screen reader accessible and should keep casual snoopers thwarted.

 ## Introduction to I38
 
-I38 is a configuration for the i3 window manager that makes it more accessible for blind people. It features audio feedback, screen reader integration, and keyboard shortcuts designed for non-visual navigation.
+I38 is a configuration for the i3 window manager that makes it more accessible for blind and low-vision people. It features audio feedback, optional screen reader integration, low-vision-friendly visual settings, and keyboard shortcuts designed for efficient navigation.
 
 Unlike traditional desktop environments like GNOME or MATE, i3 is a tiling window manager, which means windows are arranged in a non-overlapping layout. This can be more efficient to navigate by keyboard, as windows are organized in a predictable structure.
