Aaron 04fffb11d6 Run 1: bug fixes and CSS polish 
- Fix keyboard shortcuts breaking after +/- channel change (window.focus on PLAYING)
- Fix + and gear buttons not staying open (document close handler exclusions)
- Remove hotkey hint bar (moved to settings panel later)
- Title truncation: 2-line clamp for playlist and channel list titles
- sizePW: 4% buffer ensures YouTube native title never bleeds into viewport
- Mobile: hide pop-out button on ≤600px
