Technical Guide
Platform presets are defined as an array of objects with platform, post type, width, and height. On selection, the source image is drawn onto Canvas with cover-fit: source aspect ratio is compared to target, cropped to match, then scaled. Crop is centered to preserve the subject. Output is PNG for quality.
