Timing rules

• 1 dit unit = 1200 / WPM milliseconds

• Press shorter than 2 dits → dot (.)

• Press 2 dits or longer → dash (-)

• Silence of 2 dits commits the current letter

• Silence of 5 dits inserts a word space

Speed slider

• Lower WPM = more time per dot/dash and longer commit gaps

• Higher WPM = tighter timing windows

Tree

• Dots branch right from the antenna, dashes branch left

• The node matching your in-progress code glows

• Unknown codes decode as ?
