 Run with defaults:
 
 ```bash
-python3 build_printable.py --yes
+python3 build_printable.py --default
 ```
 
 The final PDF is written to `print/`. Temporary rendered images are written to `print/temp/`.
 
 ## Supported Flags
 
-- `--yes`: use default settings without interactive prompts.
+- `--default`: use default settings without interactive prompts.
+- `--mod`: use the modded print preset without interactive prompts: `600` DPI, cropped cards, and `a5-fit` boards.
 - `--dpi {300,600}`: set output resolution. Default: `300`.
 - `--paper {a3,a4,legal,letter,tabloid}`: choose paper size. Default: `a3`.
 - `--card-size SIZE`: choose card size. Use `bridge`, `mini-euro`, `poker`, `tarot`, or a custom size like `70.0x120.0` in millimeters. Default: `poker`.
+- `--board-size SIZE`: choose board size. Use `original`, `a6`, `a5`, `a4`, `half-letter`, `letter`, or a custom size like `140.0x220.0` in millimeters. Add `-fit` to preserve aspect ratio inside that size. Default: `original`.
 - `--margin MM`: set page margin in millimeters. Default: `10`.
 - `--crop`: crop black borders from cards. Default: off.
+- `--no-crop`: do not crop black borders from cards. Useful for overriding `--mod`.
+- `--gamma`: enable print-brightening gamma correction. Default: on.
 - `--no-gamma`: disable print-brightening gamma correction. Default: gamma correction on.
 - `--render-only`: render card and board PNGs, but skip page PNGs and PDF creation. Default: off.
 - `--output NAME`: write the PDF as `print/NAME`; `.pdf` is added if missing. Default filename: `blockminers_printable.pdf`.
