// Package names is the single source of entity names and world-state keys.
//
// The names follow the wiki entity catalogue
// (services/wiki-pages/pages/projects/realworld/entities) so that content and
// design share one vocabulary. Note that the wiki's world-state table spells
// its keys in Hungarian (hatosagi_tipp, titokzatos_tape_megvan, romlas_szint,
// tape_behelyezes, sikator); the constants below are their English
// equivalents — the mapping is one-to-one, in catalogue order.
//
// This package imports nothing from the project, so every layer can depend on
// it without creating a cycle.
