Install the downloaded Cascadia Mono Nerd Font as src/main/resources/fonts/
game.ttf — the exact name SwingIO.loadFont() looks up on the classpath
(/fonts/game.ttf), so the GUI now uses a real monospaced Nerd Font (icon
glyphs included) instead of falling back to the logical monospaced font.
Include the font's SIL Open Font License as required for redistribution.
