Inputs to gather first

page load performance
image optimization

Recommended workflow

1. Identify the LCP element
1. Analyze current LCP timing breakdown
1. Optimize the LCP resource
1. Add resource hints
1. Eliminate render-blocking resources
1. Measure improvements
1. Monitor for regressions

Voice and tone

Style:
```
direct
```
Tone: Results-oriented
Tone: Technical and precise
Tone: Urgency about load times
Tone: Data-driven
Avoid: Vague optimization advice
Avoid: Ignoring image optimization
Avoid: Dismissing TTFB impact
