   Online GS1 Barcode Scanner — styles

   Brand: Dynamsoft style guide (https://dynamsoft.github.io/styleguide/style-guide.html).
   This is a live-camera page, so the surface stays DARK on purpose — the
   viewfinder needs a neutral surround, which is why it uses the brand gray
   #323234 rather than the white page the tool-style demos use. Branding comes
   from the orange accents and the logo in the header.
