Vintage Baseball Grandma Wordmark

Create a two-tier stacked wordmark. Top tier: the word "Baseball" in a thin, elegant, slightly-condensed script/cursive font (similar to a vintage ballpoint signature style), arched very subtly upward left-to-right, roughly 20% the height of the bottom word, positioned directly above and slightly overlapping the top of the second word. Bottom tier: the word "GRANDMA" in an ultra-bold, wide collegiate block/slab-serif font (like a heavyweight varsity letterman font), filling nearly the full width of the canvas edge-to-edge. Replace the letter "O" in GRANDMA with a baseball icon showing visible red stitched seam curves (two curved stitch lines with small perpendicular stitch marks, hand-drawn style, not perfectly symmetrical). Apply a fine distressed/grunge halftone texture across all letters — cracked, weathered, sun-faded look with small random paint-chip breaks along letter edges, consistent with a worn vintage tee. Color: solid black ink only (single color, screen-print ready), no gradients, no outlines. Composition centered, transparent background, no shirt mockup.
