Pickers
Choose-one-from-many: pickers, comboboxes, autocomplete.
Picker · basic — items-driven collection, defaultSelectedKey
Picker · labeled — label + description; the flat collection has no sections
Assignee
Tasks route to the assignee's queue.
Select · composed — SelectTrigger/SelectValue + SelectListBox/SelectOption
ComboBox · basic — filterable input, defaultSelectedKey
ComboBox · sizes — S / M / L on the same collection
Autocomplete — headless filter provider (no styled consumer on the barrel; wraps a ComboBox)
