// the wearer's card highlights 维多利亚 (生效中), and the popup of a core bond holding 调和's +1 says 在场 n（含调和 +1） with the
// 调和 row naming 缪尔赛思 — every line inside its panel (the detail card without sideways scrolling), text ≥ 9 px on the
// phones. The strategy draft of a 标准 match (?phase=BAND_DRAFT&variant=funny, 1920×1080 and 844×390): 潘格尼尼, 克莱门莎 and
