Email blasts that land employers on a single-action page. Referrals & evals write the exact same signed_documents the Signing Center writes — nothing is bypassed. Recipients = every staff email on file for the site (primary + second + added teammates). The 🧒 Youth referrals tab flips the lane around — it emails the participants who still owe a referral signature (new assignment, never signed, or supervisor-signed-first), with a Working-Papers / Selective-Service double-check and one-tap upload link.
