Create a refined square handwritten monogram logo, with one exact character only: “F”. Center the uppercase F on a warm fine hot-press cotton paper ground; the letter occupies 56% of the canvas height with at least 55% open negative space. Draw a custom grand calligraphy F: oval-based uppercase construction, 35-degree forward slant, full pressured downstroke, tapered hairline cross-stroke, rounded upper bowl, smooth connected entry stroke, and one long word-final-style lower terminal that sweeps rightward then returns in a restrained loop beneath the letter. Keep every stroke legible at small logo size; no extra words, no border, no badge, no floral illustration, no pen, no mockup. Lettering is deep near-black ink with natural tonal variation, a fine dark wet edge, minute pooled ink at the thickest turns, and a soft satin glint where a gentle upper-left grazing light catches the strokes. Paper grain is visible but quiet, with a diffuse warm fill and soft close shadow under the ink. Front-facing flat logo presentation, sharply resolved edges, clean vector-like silhouette with authentic ink microtexture.
