An invalid byte in a grapheme is one cell, and never reaches vaxis's width
uucode joins a stray lead byte (as U+FFFD) to a following e and combining mark into one grapheme; vaxis's gwidth then counts back the replacement rune's three bytes over the one byte it stood for and overflows (gwidth.zig:62), panicking the next frame after a write of \xee e \xcc\x81 to xdata (the 9P monkey's crash-b2417c49). graphemeDisplayWidth now gives each invalid byte one cell, as surface.zig draws it, and measures the valid runs between alone.
