Fixing a few hundred clear typos with the help of Claude. Some are less important in code comments, but majority of them are in user-facing places. I manually approved 60%+ of the changes and didn't see any that were an incorrect suggestion, at worst it was potentially uncessesary, like a code comment having cant instead of can't. No RM.

 If you open a shared session while viewing the Genome Browser, it is possible to lose all of your 
 own browser settings. That is, the settings for the newly-opened session will take precedence over 
 your existing settings and will replace them. If you wish to preserve your original settings, you 
 should first save your own settings as a session before opening a new session, or open a new tab or 
 window in your internet browser before loading the new session.</p>

 There are four ways to open a shared session, depending on what information you have about the 
-session. The instructions below assume that you want to replace your current session the new
