-- Custom cloud themes (account.createTheme/uploadTheme, etc.). themes = the catalog
-- of user-created themes; document_id softly references documents (no hard foreign
-- key, to avoid coupling with the media table; a theme may outlive its blob, in
-- which case getTheme degrades to no document). settings = JSONB of
-- []domain.ThemeSettingsSpec (non-empty only for accent themes).
-- theme_user_installs = each user's installed/saved theme list.
