/*
 * File Viewer — 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
 *
 * Layout follows the generator demos: white page, corporate header, intro
 * block, card surfaces. The difference is the workspace — three panes
 * (files / preview / details) rather than one long form.
