I am sorry不要 break early. Need code not only head. Let me continue full HTML crude CSS color. Maybe generate full page in one response. Need enough detail. Let's produce high quality HTML. I need code perhaps 3000 lines? But within chars 15k-26k. I can concise CSS.
I'll craft now. Need be careful not to mention placeholder.
Full code:
```
...
```
Let's write minimal but complete.
Will include CSS in style tags. Use classes.
Important if only HTML page, no style. I'll specify.
Use
and design on imgload via CSS.
CSS: `.ph{position:relative;overflow:hidden;background:linear-gradient(135deg,#0c1f44 0%,#062766 70%)...;text-align:center}`. `.ph img{position:absolute;inset:0;width:100%;height:100%;object-fit:cover;zapply'. ;:0}`. `.ph .ph-label{position:absolute;bottom:12px left:10px...;opacity:65%}`... If image loads but img src fails path likely but real load might fail in offline; img breaks background gradient from container. It's okay broken icon. Could set .ph-ph-img opacity 0. That ensures image not visible, background gradient visible. But that violates image display. Another approach `.ph img{width:100%;height:100%;object-fit:cover;}.ph img.error, .ph-img.error{...}`Cannot detect. I'll set `opacity:0.2` if loaded? No.
I'll set background and image; if no load broken icon unnatural. I'll use img with src="img" but no actual image; broken icon maybe ugly. Perhaps generate img tag with style "text", memory no fail? Since /assets/images/hero.jpg not exists, browser error. `img.onerror="this.style.display='none'"` in JS hides error and gradient shows. Yes add onerror in every img? "this.style.display='none';" Because inline onerror not ideal but functional. In page
