label_app.py: label size presets, multi-line text with auto-fit / bold / alignment, tabbed emoji picker (rendered via Noto Color Emoji, gamma-darkened and dithered for the thermal head), live 1-bit preview, save PNG, print in a background thread. Settings persist in ~/.config/niimprint-label/. main.py is the earlier minimal GUI it supersedes.
