vocabularies

The role names of single food-storage pieces that share one slot-profile (a sealed holding vessel) and differ only by role + size: jar, storage box/container, canister, lunch box. A growing vocabulary (L13). Bread box & butter box are NOT here yet — they are deliberately non-airtight (a bread box needs airflow, a butter dish has a loose dome) so they have no sealing value and are deferred until a non-sealing cover value or a separate home exists. A multi-tier lunch carrier is NOT a value here either — it is the class LunchCarrier (it adds an exclusive tier count).

Answers the question: food storage type.
