- Items (text blocks, emoji) are placed freely: click to select, drag to
move, arrow-key nudge, rotate to any angle, resize, duplicate, fit/center
- Emoji picker now covers the full emoji set via emoji-data-python
(~1,900, 9 categories, name search, hover shows the name); thumbnails
are rendered by Pillow with Noto Color Emoji so ZWJ sequences and flags
display exactly as they print
- Designs save/open as JSON; last design restored on launch
