/* kolaj.css (W3, img_merge / img_side / screenshot_merge): the collage editor in the chosen-files state — sortable
   tiles (drag or arrow keys), the live preview that is the file, the output size line — and the side options.
   Builds on tool.css + local.css (seg, lfield, lcheck, lnote, lfacts); the look of gorsel.css's editors (W2), which
   this page does not load. The tiles are always laid out left to right (also on RTL pages): they mirror the image,
   whose first picture is on the left / at the top. Radius 0–6 px, the site's tokens only. */
