  1. I’ll inspect the image dimensions and create `framed.png` in the current directory with a 40 px white border on every side.

  2. python3 -c 'from PIL import Image; im=Image.open(\"hopper.png\"); print(im.size, im.mode)'
    output
    (128, 128) RGB
  3. python3 -c 'from PIL import Image, ImageOps; im=Image.open(\"hopper.png\"); ImageOps.expand(im, border=40, fill=\"white\").save(\"framed.png\")' && python3 -c 'from PIL import Image; im=Image.open(\"framed.png\"); print(im.size, im.mode)'
    output
    (208, 208) RGB

  4. Created [framed.png](framed.png) with a 40 px white border on every side. The resulting image is 208 × 208 pixels.

How to use it:
1. Run `deft <group>` to list commands, or `deft find "<what you want>"` to search. If it says `no command does this`, use another tool.
2. Run `deft <group> <command> --help` for options and examples.
3. `deft convert <in> -o <out.ext>` converts between formats by extension.
4. Results are one line starting with `ok`, `partial` or `error`; add `--json` to parse them. Errors include a `hint:` with the fix.

Inputs are never overwritten; pass `--force` or `--in-place` to allow it. Globs and directories work as inputs; several inputs run in parallel.

If `deft` is not installed, ask the user, then follow https://github.com/firstprayer/deft/blob/main/docs/INSTALL.md
