/*
 * Fix GridStack resize handles overlapping tile content.
 *
 * GridStack appends .ui-resizable-handle elements as direct children of
 * .grid-stack-item. They are absolutely positioned relative to that item,
 * so they sit on top of .grid-stack-item-content.
 *
 * The solution:
 *   1. Give .grid-stack-item a small inset on the edges where handles live.
 *   2. The content div fills the remaining space normally — no padding needed.
 *   3. The handles sit in the reserved gutter, never on top of content.
 *
 * Handle positions used:  se, sw, ne, nw, e, w, n, s
 * Gutter size: 8px  (matches typical ui-resizable handle size)
