// Renderer picker on the settings page. Reads + writes
// `localStorage['mobux:renderer']` ('xterm' | 'sterk'). Default 'xterm'.
//
// The page-level boot script in render_terminal_page reads this on
// load and document.write()s the matching bundle script tag. So a
// change here doesn't apply to any already-open terminal tab until
// it reloads — we show a hint to that effect.
