 ## 照片方向 / Orientation
 
-编辑照片数据源可选：横向、竖向、自动识别。自动匹配当前渲染画布 1200×1600，因此选竖向。按 EXIF 校正后的 width/height 分类，正方形不混入横向或竖向。预览、指定图片和定时随机选图使用同一筛选结果；空结果明确失败，不退回其他方向。照片不为匹配方向强制旋转或拉伸。
+编辑照片数据源可选：横向、竖向、自动识别。自动根据目标设备尺寸和旋转方向计算画布；例如 1200×1600、rotation=270 输出 1600×1200 并选择横向。手动横向输出 1600×1200，手动竖向输出 1200×1600（以当前设备为例）。照片区和底部三行文字均随画布重排。按 EXIF 校正后的 width/height 分类，正方形不混入横向或竖向。预览、指定图片和定时随机选图使用同一筛选结果；空结果明确失败，不退回其他方向。照片不为匹配方向强制旋转或拉伸。
 
-已有数据源 `orientation=null` 保持原来的全部方向，编辑器显示“不筛方向（原有设置）”；新建数据源默认自动。尺寸缓存持久化在 SQLite `photo_dimensions`，按路径、修改时间和大小失效。首次扫描读取本地图片尺寸和 EXIF，不批量生成全图库预览；后续刷新复用缓存。仅 NAS 本地源支持，WebDAV 不批量下载原图测尺寸。若将来改变原生画布尺寸，需要同步调整 auto 的匹配规则。

-Orientation options: landscape, portrait, auto. Auto matches the current portrait rendering canvas. Classification honors EXIF orientation; square photos are excluded from directional matches. Existing sources remain unfiltered (`null`) until changed. Dimensions persist in SQLite and refresh when the file changes. Local NAS sources only; no bulk original downloads from WebDAV. Empty matches fail closed. This controls selection, not photo rotation or stretching.
+Orientation options: landscape, portrait, auto. Auto follows the target device dimensions and rotation (90°/270° swap width and height). Manual direction controls both selection and rendering. Photo and caption layouts support landscape and portrait. Classification honors EXIF orientation; square photos are excluded from directional matches. Existing sources remain unfiltered (`null`) until changed. Dimensions persist in SQLite and refresh when the file changes. Local NAS sources only; no bulk original downloads from WebDAV.
