• ✅ Context Enrichers pattern
• ✅ Worker Variables pattern
• ✅ Consent management deep dive
• ✅ Tool-specific quirks (GA4, Facebook, Google Ads)
• ✅ GTM migration guide
• ✅ Comprehensive troubleshooting
• ✅ "When NOT to use Zaraz" section
• ✅ TypeScript type definitions

Preserved Content

• ✅ All original API methods

• ✅ Debugging tools
• ✅ Reference links

Progressive Disclosure Impact

Before (Monolithic)

All tasks loaded 366 lines regardless of need.

After (Progressive)

• Track event task: README (111) + api.md (287) = 398 lines
• Debug issue: gotchas.md (317) = 317 lines (13% reduction)
• Configure tool: configuration.md (307) = 307 lines (16% reduction)
• SPA tracking: README + patterns.md (SPA section) ~180 lines (51% reduction)

Net effect: Task-specific loading reduces unnecessary content by 13-51% depending on use case.
