/* Shared image kit (client/image-kit.js, views/_image-kit.cjs), 2026-10-11. Used by every image tool; owner: the kit.
 * .vt-ik-drop       drop zone (label wrapping the hidden file input); .vt-ik-over while a file is dragged over it;
 *                    add .vt-ik-drop-compact once files are in, so it shrinks to one row and the work area moves up
 * .vt-ik-mini       small copy of the preview next to the controls, visible only when the page is one column
 * .vt-ik-sources    table of sizes with their sources (rows become stacked cards on a phone)
 * .vt-ik-list/item  picked files: thumbnail, name, "before -> after" sizes, remove button (VT.imageKit.row)
 * .vt-ik-stage      preview box with a checkerboard, so transparent areas are visible; holds a canvas or an img
 * .vt-ik-surface    element the visitor drags or pinches (touch-action none: the page does not scroll under the finger)
 * .vt-ik-range      label + slider + live value;  .vt-ik-color  colour input;  .vt-ik-opt  block of options
 * Borders are 1px hairlines everywhere. */
