/*
 * Boarding Pass Generator — 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 tool-style page rather than a live-camera page, so it keeps the
 * white surface and the corporate header, unlike the scanner demos.
 * Self-contained: each Codepool demo carries its own stylesheet.
