≤4 mutually exclusive options that switch a view or filter — tab-like toggles. pill variant (default) for view-level toggles outside form chrome. bordered variant when the control sits inside a form or next to inputs/dropdowns.

Not for >4 options (use a chip group) or for form data entry (use RadioGroup).

Mix pill SegmentedControl next to bordered inputs — visual mismatch.

Firing actions from a trigger — overflow menus on cards (edit / delete / share), profile menus, contextual options. The trigger is a button (often IconDots), opening reveals items that *do something*, not items that set a value.

Not to set a form value (use Select). Don’t mix actions and values inside one menu.

Flows with 2–5 discrete steps that aren’t obvious from content. Place inside FlowHeader (top of FlowSheet) so it persists while the user moves forward/back. 1-indexed for users.

Not on single-screen modals, with 6+ steps (use "Paso 3 de 8" text instead), or for variants of one screen (don’t fake progress).

Show outside a flow context — confusing.
