Comments pinned to a point on the content: place a pin by clicking or with the keyboard, nudge it with the arrows, discuss in a thread beside it, resolve it, and find every pin in a numbered list.

Accessibility #

It exposes status semantics, with aria-pressed, aria-hidden, aria-label, aria-expanded and aria-labelledby kept in step with state. Changes that matter are announced through a live region.

KeyBehaviour
EscapeCloses or cancels, then returns focus to where it came from.
EnterActivates the focused control.

Motion #

Transitions use the shared duration and easing tokens. Under prefers-reduced-motion those tokens collapse to instant and travel distances go to zero, so state changes still happen without movement.
