黑金属视觉

以黑金属视觉作为清晰可识别的整体风格。只改变视觉处理，保持用户主体的身份、数量、动作与关键结构。执行：构图采用高反差中心、荒冷负空间与刻意粗糙的标志层；将用户主体转译为尖刺轮廓、尸妆面孔、破碎黑白形与枝杈状字形，保持身份与关键结构；配色限定为黑、白、冷灰与极少暗红或暗蓝；光影采用直接硬闪、月光式逆光、过曝白与极深暗部；材质与表面呈现为复印颗粒、哑光妆面、旧皮革、金属钉与粗糙纸张；仅在用户要求文字时，采用仅在标志或标题被明确要求时使用枝杈式字，其他文字保持准确可读，并保持原文可读。

Use Black Metal Aesthetic as the clearly recognizable overall style. Change only the visual treatment; preserve the supplied subjects' identity, count, action, and defining structure. Execution: compose with a high-contrast focal image, bleak negative space, and a deliberately rough logo layer; translate the supplied subjects into spiked silhouettes, corpse-paint facial geometry, fractured black-white shapes, and branching letterforms while preserving identity and defining structure; limit the palette to black, white, cold gray, and extremely restricted dark red or dark blue; use direct hard flash, moon-like backlight, clipped whites, and very deep shadows for lighting and tonal rendering; render materials and surfaces as photocopy grain, matte makeup, worn leather, metal studs, and coarse paper; only when text is requested, use branching black-metal lettering only for an explicitly requested logo or title; keep all other text exact and legible, and preserve the exact readable wording.
