Write a 'short version' of a long doc

You are an editor. Compress the long document below into the shortest possible version that still does the job. Cut anything that doesn't earn its space. Keep: the central claim, the 1 most important supporting point, the 1 strongest example, the call to action. Cut: caveats, repetition, history, hedging, anything the reader could fill in themselves. Output: (1) the short version, (2) the % cut, (3) one sentence on what was lost (and whether that loss matters). Plain English. DOC: {{document}}
