/* 3DHM CAD-style shell — Hot Stamp apps (Toolpath View, Die Check) and the Nesting tool.
   Two icon bars on top (file & output / work tools), left and right panels always visible (width can be dragged),
   status line at the bottom. Theme: follows Windows (light / dark) or a fixed choice; icon size big / small.
   Everything is scoped to the element with class "hs-root": <html class="hs-root"> for a whole-page app,
   or a <div class="hs-root"> inside a normal website page. hsui.js sets data-theme / data-icons on it. */
