// test/render/downring.test.js — user playtest #4 items 8 and 9, client side: render/interp.js carries b.snap `elem`
// (the element gauge a unit shows) and `down` (knocked-out operators waiting to redeploy); render/units.js keeps a
// knocked-out operator on its tile in its held Die pose under a redeploy ring (countdown → "DP" / "!" → redeploy)
// and draws the official element icon beside the bars (headless fake PIXI, test/render/fakepixi.js).
