A Morse Code Translator With Web Audio Playback and PARIS-Standard Timing

Morse timing is derived from the word "PARIS". At 5 WPM, sending "PARIS" 5 times takes exactly 60 seconds — which sets the unit duration. A dot = 1 unit, a dash = 3 units, intra-character gap = 1 unit, inter-character gap = 3 units, word gap = 7 units. At N WPM, one unit = 1200/N ms. This is the global standard.

Morse code predates digital communication by a century and a half but still runs in amateur radio, naval signaling, and emergency beacons. The encoding itself is tiny — a lookup table — but the timing is where it gets interesting.
