Technical Guide

Source image is loaded onto Canvas and resampled at each target size using drawImage. For sizes below 64px, multi-step downscaling (progressive halving) avoids aliasing. Each output is a square Canvas with cover-fit. Output is PNG for transparency. File naming follows icon-{size}x{size}.png convention.
