Output

水印风格：classic · 图片 3000 × 4000px · 水印条高 220px（占 5.5%）
字号 66px（参数行 56.76px）· 内边距 74.8px · 文本项 4 条
内容：LEICA | Xiaomi 14 Ultra | hello | 1/250s · f/1.63 · ISO 100 · 23mm
未镜像：直接叠在相机原图上即可。

摆放建议：水印条贴底、左右各留 3.4% 内边距，参数行用字重 600 更接近相机原生观感；
导出时把水印 SVG 合成到 JPEG 里（不要叠在相册预览上），才能保留原图 EXIF。

水印 SVG（viewBox 已裁到水印条，可直接叠图）：
