/*
 * Hero logo animation.
 * Targets the SVG image of the Divi Image module that has the CSS class "hero-logo".
 * Works together with hero-logo.js, which inlines the SVG next to the <img>
 * and tags each path (shield / title letters / tagline letters / specks).
 *
 * Entry  : the shield outline is drawn, then filled; letters stamp in; specks settle.
 * Scroll : --p (0 → 1) is set on the SVG by the script; letters and specks scatter,
 *          the whole logo pushes in and fades out.
