guide tier

A guide tier is one category in an archetype’s guide layout. Each tier specifies what its shards contain and what they keep out. The default archetype, the Code Repository Archetype, defines four tiers: features/, client/, developer/, and glossary/. A tier can include more than one guide.

Default guide layout defines the four tiers. Under its placement test, a shard that consumers need goes in features/ or client/, and a shard that only contributors need goes in developer/.
