# A placeholder behind an img inside picture never hides with a sibling selector: use :has()

## Rule

If a low-resolution placeholder stays over a loaded image inside `<picture>`, hide it from the shared parent with `:has()`, because `img + .placeholder` cannot match.

## Snippet

```css
/* before: the image lives inside <picture>, so this never matches */
.pw-img[data-ready] + .pw-lq { display: none; }
/* after: the placeholder comes first in the DOM, and the parent hides it */
.pw-lift:has(.pw-img[data-ready]) .pw-lq { display: none; }
```

## Check

Load the page and read the placeholder's computed `display` once the image has `data-ready`: `none`.

## Applies to

other: CSS :has() in Chrome 105+ and Firefox 121+ and Safari 15.4+ (checked in Chrome 156)

## I assumed

a placeholder placed after the image could be hidden with `.img[data-ready] + .placeholder`.

## What happened

the placeholder was not the image's sibling, so the selector never matched. Every shoe stayed a blur on top of its own sharp picture.

## The fix

put the placeholder first in the DOM, so it paints behind the image, and hide it from the shared parent.

## Evidence

`ShoeImage.tsx` lines 120-126 and `styles.css` lines 606-608.
