Turns one source image into a complete favicon set: favicon.ico (a real multi-resolution ICO container holding 16, 32 and 48px PNG-encoded entries -- not a single-size file with an .ico extension), favicon-96x96.png, apple-touch-icon.png (180px, flattened onto backgroundColor because iOS paints transparency black there), web-app-manifest-192x192.png and web-app-manifest-512x512.png (optionally padded to Android's maskable safe zone -- the artwork shrunk to a centred 80%-width square on the background colour, reproducing the source tool's square padding rather than clipping to the actual inscribed-circle safe area), site.webmanifest, and the exact 5-line HTML <head> snippet (favicon.ico link, favicon-96x96.png link, apple-touch-icon link, apple-mobile-web-app-title meta, manifest link) ready to paste. A non-square source is centred on a transparent square canvas first, so nothing is stretched. Ported from GO AI's browser-based favicon tool, run server-side with @napi-rs/canvas instead of a DOM <canvas>. Every PNG and the .ico are small (a few KB to worst-case a couple hundred KB), so all six files are returned individually rather than zipped -- each name matters (favicon.ico and site.webmanifest belong at the site root) and there is no batching benefit to a ZIP at this size. The JSON result carries the manifest JSON text, the HTML snippet text, a per-file table of what each output is for, and a warning when the source is smaller than 512px on its longer side (the 512 icon will be upscaled). Fails with a clear message rather than throwing if the input cannot be decoded as an image.
