// Regression guard for the sidebar folder context-menu layout: the two refresh
// actions (scan this folder, check for updates) sit on top, the folder
// operations form a single group, and the destructive entry stays last behind
// its own divider. SidebarManager gates those groups per page and collapses the
// dividers when a group is hidden, so a reorder here also changes what the
// recipes page shows.
