  Opera Ads' client-side surface is an ad-rendering surface, not a dashboard or
  form-element library. Three families: a drop-in web JS tag that renders into
  an <ins> element, header-bidding adapters that plug into Prebid.js and Prebid
  Server, and the mobile SDK ad views/formats. Distinct from packages/ — the
  SDK distribution artifacts are recorded there; the renderable surfaces are
  recorded here.
families:
  - name: Web JS Tag
    kind: script-tag
    description: >-
      Opera Ads JS SDK. A single async <script> plus an <ins> element carrying
      data-adx-slot; the ad renders into the <ins>. Rendering is triggered by
      pushing the element id onto the global adsbyopera queue.
    loader: https://res.oa.opera.com/x/oa.js
    versioning: unpinned — the loader URL carries no version segment
    embed: |
      <script src="https://res.oa.opera.com/x/oa.js" async></script>
      <ins id="ad_1" data-adx-slot="<your-slot-id>" style="display: inline-block; width: 300px;"></ins>
      <script>(adsbyopera = window.adsbyopera || []).push("ad_1");</script>
    attributes:
      - name: data-adx-slot
        description: Opera Ads placement (slot) ID.
      - name: id / class="adsbyopera"
        description: >-
          Either address a single <ins> by id, or mark elements with the
          adsbyopera class and push an empty object.
    guidance: >-
      Always set an explicit width on the <ins>; display:inline-block is
      expected. Position with ordinary HTML/CSS.

  - name: Header Bidding adapters
    kind: bidding-adapter
    description: >-
      Opera Ads participates in web header bidding through the standard Prebid
      stack rather than a proprietary component. The OperaAds bid adapter is
      built into the Prebid.js download builder and Prebid Server.
