/**
 * SIT Recycling Enterprise V6.4.2 — refined Social Impact sections layered onto the V6.3.17 Launch Clarity Foundation.
 *
 * The existing public hero and overview remain unchanged. This layer starts at
 * the participant section and creates a calmer, more editorial hierarchy for
 * the remainder of /social-impact/ only.
