Components

Which components the system carries: its inventory, picked from the catalogue.

The five answers

Question	Answer	Why
Which component families does it need?	Core, plus content and media	Product teams build sign-up and account forms, plus product pages with questions and faces.
How far does the inventory reach?	What today's screens use, plus what the next ones will likely need	Three product teams find their next parts ready, kept by one platform team.
How does a component earn its place?	Its family is in the roles, so product teams find it ready	Product teams find a whole family ready instead of asking one by one.
When does a component get another look?	Also for emphasis and size	Variants for emphasis and size let each brand feel present without new components.
Where do components do the most work?	Sign-up and account pages	Most components sit in sign-up and account pages.

When to use what

Situation	Use	Not	Why
No component in the inventory fits	a component from the inventory with brand tokens	a component made for one brand	Brands change primitives, never components; one brand-only part breaks the shared library.
