/*
* HOW IT FINDS THE ORIGINAL FILE (three tiers, cheapest first)
* 1. DOM attribute -> e.g. danbooru's img[data-file-url]. No extra request.
* 2. Site JSON API -> booru dapi / post.json?tags=id:N => file_url + tags
* 3. Post page HTML -> fetch the post page, read <meta property="og:image">
* plus its tag links. Universal, needs no API key.
*
* TO ADD A SITE: append one object to ADAPTERS. Minimum: host, itemSel,
* idFrom(), linkFrom(). Add origFrom()/tagsFromDom() for zero-request mode and
* api()/parseApi() for tier 2. Tier 3 is automatic for any adapter.
