-- Selectors for the companion window content. Six display modes:
--   styles      -- user-created style + smartset collections
--   shopping    -- shopping list collections
--   snapshots   -- saved placed-decor snapshots
--   themes      -- pre-authored Room Concepts (StyleDefinitions, tier="thematic")
--   collections -- pre-authored Useful Collections (CollectionDefinitions)
--   recent      -- live placed decor (session.styles.placedDecor)
--
-- Sidebar = collections matching current mode (or recent items flat for "recent").
-- Selecting a sidebar row sets session.ui.companion.selectedItemID.
-- Grid = items in the selected collection (or placedDecor map for "recent").
--
-- Reuses existing data sources (Styles/Collections StaticData, account.collections,
-- session.styles.placedDecor) -- companion is a different view onto Styles-tab data.
