/* =========================================================================
   ScannerQRCodes — main stylesheet

   Visual language: a tinted mint band carries the header and the tool, plain
   white carries the editorial content below. One deep plum accent does all the
   work (buttons, links, active states), teal is the quiet second voice.
   Headings are near-black and heavy; surfaces are white cards with hairline
   borders and a very soft shadow rather than coloured fills.
