44## Progressive Disclosure Impact
45 
46### Before (Monolithic)
47All tasks loaded 366 lines regardless of need.
48 
49### After (Progressive)
50- **Track event task**: README (111) + api.md (287) = 398 lines
51- **Debug issue**: gotchas.md (317) = 317 lines (13% reduction)
52- **Configure tool**: configuration.md (307) = 307 lines (16% reduction)
53- **SPA tracking**: README + patterns.md (SPA section) ~180 lines (51% reduction)
54 
55**Net effect:** Task-specific loading reduces unnecessary content by 13-51% depending on use case.
