/**
* One entry in any project knowledge list.
*
* Notes and memories drifted into two different-looking rows in the same panel:
* one a bare block of text opened by clicking the text, the other a bordered
* card opened by a chevron. They hold different content but they are the same
* kind of thing to read, so they share this shell and this interaction.
*
* A collapsed card opens on a click anywhere on it — the whole card is the
* target, not a chevron the user has to aim at. An expanded card closes only
* through its collapse action, because its body is editable and a stray click
* in the text must not throw the editor away.
