When zooming, the page was scaling from a fixed point causing content
to appear to "move through" the viewport like a 3D perspective effect.
This made the zoom feel disorienting as the visible content would shift.
Solution: Proportional scroll compensation
- Track current scale before applying new scale
- Calculate scale ratio (newScale / currentScale)
- Adjust scroll position by multiplying by scale ratio
- Example: scrollTop 1000px at 100% → 1500px at 150%
Benefits:
- Content you're viewing stays in the same visual position
- Zoom feels more like "magnification" than "perspective"
- Smooth, stable zoom experience without content shifting
- Eliminates the "going through me and getting farther" effect
Technical changes:
- Extract current scale from transform property via regex
- Calculate proportional scroll adjustment
- Apply synchronized transform + scroll in requestAnimationFrame
- Enhanced CI/CD pipeline with coverage reporting, benchmarks, and artifact uploads
- Implemented rate limiter IP validation with proxy support and spoofing protection
- Added extensive Makefile test targets for coverage, benchmarks, and continuous testing
- Expanded middleware chain with request validation, size limits, and suspicious activity logging
