@* daisyUI Collapse: https://daisyui.com/components/collapse/ . The open state lives in C# (@bind-IsOpen) and is
|

rendered with collapse-open / collapse-close; clicking the header (or Enter/Space on it) toggles it. neo-raised
|
||
|

gives it the neumorphic panel look (see Styles/neo.css for why it isn't a @utility override). *@
