  wine-club-customize-data.liquid
  Server → client data contract for the customization portal.

  Resolves: logged-in customer → their tier → the active (open) cycle → that
  tier's pool. Emits a single JSON blob consumed by wine-club-customize.js.

  Prices are read LIVE from Shopify variants (decision #3) — never stored.
  Requires the customer to be tagged/segmented with their tier, e.g. a customer
  tag `wc-tier:classic-3` set by Appstle/Flow on subscription. Adjust the
  `customer_tier` lookup to match how Appstle exposes the plan on the store.

  Inputs (assigns expected before render):
    - active_cycle : a wineclub_cycle metaobject (status == "open")
    - tier_pool    : the wineclub_tier_pool metaobject matching customer's tier
