ultra-photorealistic primeval equine, posture calm and stable, photographed with maximum zoological precision. Evolution-driven microtexture of the coat:  Hair strands display real cuticle scales, catching diffused forest light;  Tiny particles of pollen, spores, and forest dust trapped naturally between layers of the coat;  Subtle wave patterns in dorsal hairs caused by grouped follicle growth;  True dun gene expression: diluted base pigment with molecular-level gradients from beige to charcoal. Hyper-real markings: brown Ocapi stripes with sub-millimetric tonal shifts inside each band; hair density differences create naturally irregular boundaries;  Zebra shadow-stripes caused by density variation rather than pigment visible only when light grazes the dorsolateral surface;  Oryx mask formed by layered pigmentation, heaviest along the zygomatic and masseter curves;  Subtle evolutionary saddle mark  on the shoulder with non-uniform pigmentation. Microdetails:  Fog microdroplets adhered to individual hairs, refracting soft silvery light;  Regions of partially wet fur with altered texture;  Visible skin pores and natural micro-scars beneath short facial hairs. Environment: temperate forest, fog-diffused midday light at 12:22, suspended particles visible in volumetric beams. Shot on 50mm, f/1.8, ISO 160, forensic-level zoological resolution.
