/* Online Boarding Pass Scanner — Codepool demo styles.

   Visual language follows the Dynamsoft style guide
   (https://dynamsoft.github.io/styleguide/style-guide.html):
     - brand orange  #FE8E14  (CTA / accent only)
     - brand gray    #323234  (headings, body copy)
     - grays         #606060 #999999 #CCCCCC #DDDDDD #F5F5F5
     - headings      Oswald        body copy  Open Sans

   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. The results overlay is
   the one white surface, because it carries dense structured text. */
