  * Single self-contained module (same shape as ext.itemLevelSlider /
  * Mounts into <div id="eql-item-score-table">. All data access goes through
* ext.classSlotEquip). Paste into User:<you>/common.js, then create a page
  * ACTIVE_DATASOURCE so a server-side Special:ItemScoreTable can later replace
* containing:  <div id="eql-item-score-table"></div>
* ClientDataSource with a one-line change.
*
  * Data access goes through ACTIVE_DATASOURCE so a future server-side
* Special:ItemScoreTable can replace ClientDataSource with a one-line change.
*
* RELOADING AFTER AN EDIT: MediaWiki serves the user JS bundle from a server-side
* ResourceLoader cache keyed by a version hash. After you save common.js the hash
* can take a few minutes to recompute, so a browser hard-refresh (Ctrl+Shift+R)
* alone may still run the OLD code. Reliable ways to force the new version:
*  1. Append &debug=true to the page URL (bypasses the RL cache/minifier), or
*  2. Visit  index.php?title=User:Chonx/common.js&action=raw  once, then reload, or
*  3. Run this in the console to eval the freshest copy immediately:
*      fetch('/index.php?title=User:Chonx/common.js&action=raw&_='+Date.now())
*        .then(r=>r.text()).then(t=>eval(t));
