+ * ShrinkVertically -- "Auto adjust" mode. Measure the collapsed board live and set the
+ * --sv-shrink-offset CSS variable so the columns exactly fill the remaining viewport and the
+ * native right-side vertical scrollbar is not needed. Loaded only when the setting is on
+ * (Settings -> Shrink Vertically); it overrides the static offset injected by layout/variable.php.
+ *
+ * The collapsed column height is calc(100vh - var(--sv-shrink-offset)). To fit the screen we need:
+ * offset = (task-list top, i.e. the chrome above) + (horizontal scrollbar below) + a small margin
+ * so column_bottom + scrollbar stays within the viewport. Both terms are measured from the DOM, so
+ * this adapts to any screen size, theme, or header height.
+ *
+ * Re-measures on resize, on collapse/expand (a class toggle), and after a board refresh
+ * (BoardDragAndDrop replaces #board-container -- so, like the other plugins, the observer is bound
+ * to the STABLE parent, not to the container that gets swapped out).
