Rendering Foto Seni ASCII Berbasis Kontur Tepi

Apply an edge-aware ASCII art rendering effect to the reference photo. Drive character placement and density directly by the photo's tonal contrast and contours. Form dense character clusters along natural silhouette lines, edges, and high-detail areas such as hair strands, fabric folds, and background structures, while leaving smooth, low-contrast areas clean with minimal texture. The characters should actively trace contours rather than appearing as a uniform overlay. Render in a classic [green-on-black or grayscale] palette using the character set [@ # % & * + . :] with [medium] overall density, keeping the reference photo clearly legible underneath.
