Notification centre
A React component in Beamline's Feedback category.
Updates that wait to be read: a bell with the unread count opens All / Unread, new and earlier groups, and per item mark read or dismiss.
Use it for
- Mentions, results and alerts people read later.
Not for
- Immediate feedback on an action (toast).
Anatomy
- bell with count
- panel header (filter, mark all)
- groups
- item (icon or avatar, title, line, time, unread dot, actions)
- empty state
States
- unread
- read
- filtered
- empty
Keyboard
- Tab through items and their actions
- Escape closes
Motion
The panel grows from the bell. Opens out of its trigger (_shared/overlay.module.css, source morph): the layer starts as the trigger's own box, offset onto it, and grows; the side next to the trigger is there at once so the nearest rows read within the ruled 90 ms, the far side settles by ~200 ms, content fades in over 90 ms; it closes back into the trigger in 180 ms. Until it has grown the press that opened it cannot land on a row. Reduced motion: it appears.

- Alert: A message that stays until it is dealt with: what happened, what to do, an action; danger and warning are announced; dismissing folds its height away.
- Announcement bar: A banner across the top for news and offers: messages take turns, a countdown ticks, and dismissing folds it away and can remember it.
- Empty state: What a place will hold and the first step to fill it, instead of a blank; a compact size for panels and filtered tables.
- Progress: How much of a known task is done, or a moving bar when the length is unknown, with an optional label and value.
- Skeleton: Holds the shape of content while it loads, then crossfades into it, so nothing jumps.
- Spinner: A ring that spins while work runs and closes into a drawn check or cross when it ends.
- Usage meter: An allowance and what fills it: one bar split by source, the room left, a warning near the limit and the overflow in its own red well past a notch at the…
