Mode: built-in image generation, followed by built-in image editing.

Initial generation prompt:
Create one transparent PNG sprite atlas of FOUR wide rectangular dark medieval board-game UI buttons in an exact 2-column by 2-row grid. Canvas 1536 by 1024, four equal 768 by 512 cells. Each cell holds one complete horizontal button tightly centered, identical size and aspect ratio about 3:1, with generous transparent separation; nothing crosses cells. Realistic miniature materials: aged hammered antique-gold filigree frame, very dark midnight-blue leather inset, subtle beveled edges and warm gold highlights. Each button includes a small physical gold icon at left and very clear, LARGE gold serif text at right. Text must be baked into the generated image and legible when each button is 110 by 40 pixels. Top left: small antique padlock icon and two lines of exact text "OFFLINE" and "LOCAL MEMORY". Top right: open illuminated rulebook icon and exact two-line text "HOW TO" and "PLAY". Bottom left: tiny brass hourglass with sand and exact two-line text "CLEAR" and "SESSION". Bottom right: rolled parchment with a plus seal and exact two-line text "OPEN" and "STATEMENTS". No other words or marks. Flat straight-on readable UI presentation, rich tactile gold and leather texture, not vector graphics. All four full buttons contained in their cells. Genuine transparent alpha background outside the buttons. No scenery, no watermark.

Edit prompt:
Edit only the background of this four-button 2x2 sprite atlas. Preserve all four physical gold-framed buttons, their exact lettering, icons, dimensions, positions, colors, edges, and textures pixel-for-pixel as closely as possible. Remove every brown glowing background area outside the buttons and replace it with genuine transparency (alpha zero), including the empty space between the four buttons. Keep the dark midnight leather interior of each button opaque. No other changes. Output a PNG with actual alpha transparency, same 1536 by 1024 canvas and grid. Do not draw a checkerboard.

The selected generated result retained some background around its edges. The page displays cropped portions of the original raster atlas; it does not replace the generated buttons with vector artwork.
