/* PDFlyHQ — tools/edit-pdf/options.css
   File card + editor toolbar + page canvas with a positioned-DOM-element
   overlay (text/rectangle/ellipse/line). Matches _Options.cshtml. JS
   contract: #file-name, #file-size, #btn-remove-file, .tool-btn[data-tool],
   #opt-color, #opt-font-size(-value), #opt-stroke-width(-value), #opt-fill,
   #btn-delete-element, #btn-prev-page, #opt-page-select, #btn-next-page,
   #editor-canvas, #editor-overlay, #btn-save, #btn-back
   (ElementManager.js / EditorCanvas.js / index.js).

   Every added element is a real positioned DOM node (.editor-el), not a
   canvas draw — left/top/width/height are px derived from ratios of the
   canvas's own rendered size, same technique as Sign PDF's signature
   placement overlay, which is what lets EditorCanvas.js drag any element
   type with one shared pointer handler. */
