ComboBox
Carbon-spec single-select with free-text filtering. Built on cmdk + Popover. Distinct from Select (no free-text) and MultiSelect (multi).

When to use
- A single-choice list of >7 options where the user benefits from typing to filter (countries, projects, tags).
- Pickers where the option labels are user-readable and substring-search is the right mental model.
When not to use
- ≤7 fixed options where filtering adds no value → use `Select`.
- Multiple selections → use `MultiSelect`.
- Async / paginated server-side options at scale → consider building a
<CommandPalette>-style remote-source variant; ComboBox holds the full option list in memory.
