  Client-side / embeddable payment UI surfaces PAY.JP provides for collecting
  card data without raw PANs touching the merchant server. Distinct from the
  server-side SDKs in packages/payjp-packages.yml.
components:
  - family: payjp.js (v2)
    kind: browser-tokenization-library
    loader: https://js.pay.jp/v2/pay.js
    docs: https://docs.pay.jp/v2/guide/basics/how-to-collect-card-information
    note: >-
      JavaScript library that mounts secure card input fields (Elements-style)
      and exchanges entered card data for a single-use token using the
      publishable key. Supports 3D Secure and Apple Pay flows.
  - family: Checkout
    kind: hosted-drop-in-button
    loader: https://checkout.pay.jp/
    docs: https://docs.pay.jp/v1/checkout

      returns a token to the surrounding form — the lowest-integration option.
  - family: Mobile SDK card forms
    kind: native-ui
    docs: https://docs.pay.jp/
    note: >-
      iOS (PAYJP) and Android (jp.pay:payjp-android-cardform) ship native card
      input / card-scan UI that tokenizes on-device; catalogued as SDKs in
      packages/payjp-packages.yml.
