fix: replace tangled umbrella/rain metaphor with direct description
The old version ("the university is the umbrella, the tool is the rain") made the tool sound like the threat being sheltered from, which inverts the meaning. Replaced with direct prose: salary → time → tool, nobody planned it, it happens in the gap between paid work and actual work.
