1. Browser Cache Fix:
- Added ?v=4.0 to main.js to force browser reload
- This ensures new comparison/waterfall UI loads
2. Remove ALL Throttling:
- Disabled Lighthouse network throttling (rttMs=0, throughput=0)
- Disabled CPU throttling (cpuSlowdownMultiplier=1)
- Set throttlingMethod to 'provided' (no simulation)
- Applies to both mobile and desktop tests
3. Backend Default Already Fixed:
- isMobile defaults to false (desktop) matching frontend
