/*!
 * Multi-Step Form Master - progress-styles.css
 * Version 1.0.0
 *
 * Progress indicator styles. The engine renders the same markup for every
 * style; pick one with data-msf-progress on the form:
 *
 *   data-msf-progress="steps"   numbered steps with labels (default)
 *   data-msf-progress="bar"     slim top bar with step count and percentage
 *   data-msf-progress="dots"    minimal dots, the current one stretches into a pill
 *   data-msf-progress="sidebar" vertical list; place <nav data-msf-progress> in a sidebar
 *   data-msf-progress="circle"  percentage ring with the current step name
 *   data-msf-progress="false"   no indicator
 *
 * Rendered markup
 *   <nav class="msf-progress msf-progress--{style}">
 *     <ol class="msf-progress__steps"> <li class="msf-progress__step is-complete|is-active|is-upcoming"> ... </ol>
 *     <div class="msf-progress__ring"> svg + percentage </div>   (circle style only)
 *     <div class="msf-progress__bar"><span class="msf-progress__fill"></span></div>
 *     <p class="msf-progress__meta"> count / current title / percent </p>
 *   </nav>
 *   The fill width comes from the --msf-progress custom property (0% - 100%).
