Art style: Dark Fantasy.
Full-length view, the entire figure visible from head to feet, standing upright, centered in the frame. Agata, a wise elderly grandmother in her early seventies, slight and slender but straight-backed, with a soft lined face, pale rosy skin, warm crinkling hazel eyes and a gentle knowing half-smile. Silver-grey hair swept into a loose low bun, a few strands escaping around her temples. She wears a long charcoal wool shawl over a deep plum ankle-length dress with fine embroidered trim, a small amber pendant at her throat, and worn leather lace-up ankle boots. In one hand she holds a sealed dark envelope marked with a shadowy crest; the other rests over her heart. She stands in a dim stone cottage doorway, candle-lit, pale moonlight spilling across the threshold behind her, faint mist curling around her hem.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Dark Fantasy" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Dark Fantasy". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Dark Fantasy" idiom, not in any other medium.
