 * Bootstrap's .offcanvas-lg resets position to static at >=992px (so it can sit
 * inline without JS). This app relies on a permanently fixed sidebar instead, so
 * that reset is overridden here to restore fixed positioning + the hide/unhide
 * toggle. Toggling `left` (not `margin-left`) avoids the over-constrained box
 * model that would otherwise make the browser discard the margin.
