// Regression tests (Node) of user playtest #6, client-UI items (workstream WD):
//   6  the 机变 道具补给 overlay showed only icon, name and tier on each card — no effect text (the user's Android,
//      756×366 CSS px: the description sat below the fold of a 105 px card and was clipped). The cards now use the
//      official layout (research 06 §11.5 / the official 机变 screenshots): a framed icon with the name beside it, the
//      description across the card under both, left-aligned; the description is the item's / effect's official rich text
//      (the same text as the detail card: items.json / effects.json `descRaw`), even when the server card carries the
//      plain `desc`. The taker's badge is the round avatar alone (official) and a taken card's name keeps clear of it.
//      The on-screen check (every card's text inside its card, taken or not, no name under the badge, at the phone
//      viewports down to 640×360 and on desktop) is the browser test test/ui/playtest6-ui.e2e.test.js.
//  10  on phones the second tap on the armed shop card's 确认购买 strip did nothing: the card's ⓘ corner (invisible on
//      touch, opacity 0 without hover) had a 44 px touch hit area (css/devices.css — its 30 px override lost on
//      specificity) over the bottom-right quarter of the 67 × 97 px card, right half of the strip included; a tap there
//      re-opened the detail (stopPropagation) instead of buying. The ⓘ is gone (official cards have none: the first tap
//      selects and shows the detail, the second confirms); a tap anywhere on a card is the card's tap, and a card that
//      cannot be bought now (bar not editable) opens its detail instead.
