Popovers
The Popover API: light-dismiss, top layer and toggling come from the platform. CSS Anchor positioning places them when supported.
The signal dot
Live means happening now — a stream, a current lesson, an active build. One dot per surface, never decoration.
[popover] + .pop — click outside or ESC dismisses; anchored where supported
| Class | Does |
|---|---|
popovertarget="id" | the trigger, no JS |
.pop__head / .pop__body | title strip + prose |
.tip (tooltips page) | for one-liners — a popover earns its title |
