## JavaScript
```js
(function(){
  var card = document.getElementById('pc-19-card');
  var btn = document.getElementById('pc-19-toggle');
  if(!card || !btn) return;
  btn.addEventListener('click', function(){
    var open = card.classList.toggle('is-open');
    btn.setAttribute('aria-expanded', open ? 'true' : 'false');
  });
})();
```

How this works

The reveal uses the modern height-animation pattern: the hidden section is a grid whose grid-template-rows animates from 0fr to 1fr, with the inner content set to min-height:0 and overflow:hidden. Unlike a max-height hack this animates to the content's true height with correct easing and no guesswork.

A tiny JS handler toggles an is-open class and flips aria-expanded for accessibility; the chevron rotates and the card's margin animates in tandem. With JS off the card still shows the header, and the extra detail can be revealed by default as a graceful fallback.

Make it yours

  • Change the expand speed/curve via the grid-template-rows transition on .pc-19__reveal.
  • Recolour the accent teal used on the avatar, chevron and links.
  • Add more revealed content — it animates to the correct height automatically.
  • Swap the toggle for hover by driving is-open from a CSS :hover/:has() state instead.
  • Expand-by-default for no-JS users by adding is-open in markup and removing it via JS on load (progressive enhancement).

Gotchas — read before shipping

  • The inner content must set min-height:0 or the 0fr row won't collapse fully.
  • grid-template-rows animation needs Chrome 107+/Safari 16+; older browsers jump instantly (still functional).
  • Keep aria-expanded in sync with the visual state so assistive tech announces the change.

Animating grid-template-rows needs Chrome 107+/Safari 16; degrades to an instant toggle.
