/*
 * Outbound click tracking for Plausible.
 *
 * Sends two custom events so affiliate clicks can be separated from ordinary
 * outbound links — and so a new partner can be added by editing AFFILIATES only:
 *
 *   Affiliate Click  props: network, destination, destination_path, placement, link_text, lang
 *   Outbound Click   same props (network = "none")
 *
 * Goals must exist in Plausible (Settings -> Goals -> Custom event) with exactly
 * these names: "Affiliate Click" and "Outbound Click".
 *
 * Adding a partner: AFFILIATES["host.tld"] = {network: "short-name"}.
 * Links carrying rel="sponsored" are treated as affiliate even when unlisted.
