The Drop mark.水滴标识。
A teardrop with a B silhouette knocked out — silver by default, drawn from real metallic gradient stops.一颗水滴，B 字内嵌镂空——主用银色，由真实金属渐变止点构成。
02 · Drop
Surface tension — water finding its level. The B is carried as a hollow, never drawn as a letter.表面张力——水自寻其位。B 字以镂空承载，绝不作为字母绘制。
On dark surfaces.深色背景。
Same silver gradient — the metal reads cooler against charcoal. No outline or recolouring.同一银色渐变——在深底上读起来更冷。不加描边，不重新上色。
Size ladder尺寸阶梯
Render between 24px and 240px. Below 20px the B silhouette breaks; use the wordmark alone.建议 24px 至 240px 之间使用。小于 20px 时 B 镂空会糊，请改用单独 wordmark。
Metal variants金属变体
Silver is the primary mark. Use the others only when paired with surfaces that demand a different temperature.主用银色。其余仅在与不同色温背景搭配时使用。
Lockups组合锁定
The mark sits 14px from the wordmark. The wordmark x-height roughly equals the mark’s waist.标识与字标间距 14px。字标 x-高度约等于水滴腰宽。
