/*
 * OrganonTweaks -- clicking a task title opens the edit modal instead of the read-only card view,
 * reusing Kanboard's own modal opener (KB.modal.open).
 *   - Board: the title is a link, and a hidden marker rendered next to it (only when the user may
 *     edit) carries the server-generated edit URL.
 *   - Card view: the title (#task-summary > h2) opens the same modal via #task-view's data-edit-url,
 *     but only when the user may edit -- detected by the presence of the sidebar "Edit" action.
 *
 * A capture-phase delegated click runs before Kanboard's own handlers, survives the board's AJAX
 * re-renders, and stops both the link navigation and the card's own click.
