# 21 — Quick-add registry

## Goal

A single global `+` button on the dashboard (and a `cmd+k` palette anywhere) that lists actions contributed by modules.

## Depends on

- 20

## Scope

- `QuickAddAction` type: `{ id, label, icon?, shortcut?, run: () => void | Promise<void> }`.
- Modules register via manifest. Registry exposes a sorted list.
- UI: floating `+` on dashboard opens a sheet of actions; `cmd/ctrl+k` opens a command-palette-style modal (use `cmdk` package).
- Default actions: New event, Add to shopping, Add to tasks, New note.

## Out of scope

- Fuzzy search across data (search adapter is a later concern).
- Action history / recents.

## Acceptance criteria

- [ ] Adding a new module that registers a quick-add appears in both the FAB sheet and the cmd-k palette without touching core.
- [ ] Keyboard navigation works in the palette (arrows + enter + escape).
