TASK: Build the wine-club data model in the Shopify Admin UI (Settings → Custom data).
You have collaborator access to the store "Maison Fayard" (grs60a-y0.myshopify.com). This
is a collaboration store — do NOT try to create API tokens or use GraphQL; everything here
is done by clicking in Settings → Custom data. Work only in this store's admin.

Field KEYS must match exactly (app code reads them). After typing each field's display
name, EDIT the auto-generated "key" so it matches the Key column below. For every
metaobject definition, enable "Storefront access" (expose to Storefront API) and turn on
the publishable / "entries can be published" option.

ORDERING (avoids reference chicken-and-egg):
  Step A: create metaobject "Wine Club Tier Pool" but SKIP its "Cycle" and "Upgrade
          target" fields for now.
  Step B: create metaobject "Wine Club Cycle" (its "Tier pools" field can now reference
          Tier Pool, which exists).
  Step C: edit "Wine Club Tier Pool" and ADD the "Cycle" and "Upgrade target" fields.

| Wine club selection | wineclub.selection  | JSON | Storefront read; admin read/write   |

=== THEN: seed data (PAUSE for the user's confirmation before creating entries) ===
1) Create one "Wine Club Cycle" entry: name="Q2 2026", cadence="quarterly",
   open_at=2026-04-15, close_at=2026-05-30, status="open". (Confirm real dates.)
2) Open the store's Products list and show the user every wine with its title + price, so
   they can say which wines are the DEFAULT box vs SWAP pool per tier. Do NOT guess.
3) After they confirm, create 4 "Wine Club Tier Pool" entries (use the product PICKER for
   default_wines / swap_pool — no IDs needed). Set each entry's handle to <cycle>-<tier>:
   | handle             | tier      | tier_label                | bottle_count | base_price | upgrade_target |
   | q2-2026-classic-3  | classic-3 | Classic Club · 3 bottles  | 3            | 150.00 USD | q2-2026-reserve-3 |
   | q2-2026-classic-6  | classic-6 | Classic Club · 6 bottles  | 6            | 300.00 USD | q2-2026-reserve-6 |
   | q2-2026-reserve-3  | reserve-3 | Reserve Club · 3 bottles  | 3            | 400.00 USD | (leave empty)     |
   | q2-2026-reserve-6  | reserve-6 | Reserve Club · 6 bottles  | 6            | 800.00 USD | (leave empty)     |
   Set each pool's "cycle" field to the Q2 2026 cycle entry.
   (Magnum $1,300 is BI-ANNUAL, not quarterly — flag it to the user, don't add it here.)
4) Edit the Q2 2026 cycle's "tier_pools" field to list all pools you created.

REPORT AT THE END: which definitions were created, the wine product list you found, the
pools you seeded, and which wine products still need wineclub.vintage / wineclub.wine_type
/ wineclub.catalog_group set.
