/* Invoice generator (olano.sg/tools/invoice-generator).
   The editor uses the shared tool skin and /styles.css tokens, so it follows
   both themes. The invoice itself is drawn as a sheet of paper in both themes:
   its colours are the site's own light-theme tokens from /styles.css
   (:root[data-theme="light"]: --bg-elev, --text, --text-2, --border, --bg,
   --accent), restated here because a printed invoice is dark ink on white
   paper whichever theme the visitor browses in. */
