/* QuickPassMaker Design Studio — Fabric.js editor.
   Dark, vibrant theme to match quickpassmaker.com: near-black surfaces,
   magenta (#FF3AF2) chrome accents, yellow (#FFE600) primary CTA, cyan/purple
   highlights, thick borders + hard offset shadows. Responsive: on phones the
   4-column layout collapses to a full-screen canvas with a bottom tool-rail and
   slide-up bottom sheets for the tool panel + the object inspector. */
