Collector shipping slice pending

Shipping notes are not wired up yet

This route now matches the OverPower shell, but the exact shipping timelines, packaging standards, combined-order handling, and return guidance still depend on checkout and fulfillment design.

What comes next

  • Document shipping speed, packaging expectations, and combined-order handling for singles.
  • Define damaged-card, return, and preorder language that fits collector expectations.
  • Keep the eventual policy text aligned with nat20-api checkout and fulfillment rules.
