/**
 * dw-publications.js — canonical DW Shopify sales-channel (Publication) list.
 *
 * SOURCE-FIX for the GMC $4.25 sample-leak (Steve policy, 2026-07-08):
 *   Shopify's "Google & YouTube" channel auto-syncs each published product's
 *   minVariantPrice to Merchant Center. On DW that min is almost always the
 *   $4.25 "-Sample" variant → Google advertises $4.25 on a real-roll product →
 *   price_mismatch DISAPPROVAL. Every onboard/go-live script publishes new SKUs
 *   to ALL 13 publications, INCLUDING Google (29646651457), so every new import
 *   re-leaks $4.25 onto the channel. That is the re-leak vector.
 *
 * THE FIX: new SKUs must NOT land on the Google & YouTube channel. Google is fed
 *   exclusively by the CONTROLLED TSV feed (build-google-feed.js → Merchant
 *   Center primary datasource), which drops the sample variant and emits the real
 *   (highest) price. So channel membership on Google is intentionally empty.
 *
 * DEFAULT export ALL_CHANNELS_NO_GOOGLE excludes 29646651457. Onboard scripts
 *   should publish to this list. Opt back into Google only if you have a reason
 *   AND the product is genuinely sample-only (its price IS $4.25) — see
 *   channelsFor() below.
 *
 * Reversible: to restore the old behavior, import ALL_CHANNELS_WITH_GOOGLE
 *   instead, or pass {includeGoogle:true} to channelsFor().
