You are an SVG icon designer. Create a minimal icon for a personal blog brand named “Harvestasya.” Concept: fuse a wheat/seed motif (harvest, collecting) with an upward-growing tower / world-tree silhouette (mythic, rune-like vibe). Composition: square 1:1 canvas; centered; an upward-tapering tower-shaped silhouette. Inside the tower, place 4–5 seed/grain shapes (small ovals or teardrops) in a vertical stack—reading both as a wheat ear and as “knowledge nodes.” Add a tiny leaf or small glow dot at the top. Add a very short base line or small semicircle base at the bottom. Style: ultra-minimal, geometric, no gradients, no shadows, no filters, no complex textures. Output requirements: Output only one <svg> element (no explanation text). Use viewBox="0 0 256 256"; transparent background. Use a single-color fill: default fill="currentColor" (so CSS can control color). Prefer <path> shapes; keep nodes minimal; crisp edges. No text, no embedded images, no external links.
