	// PartLabel names each modern-lectionary section's heading label word,
	// keyed by liturgy.Section.PartID (pierwsze_czytanie, psalm,
	// drugie_czytanie, aklamacja, ewangelia). The pl entries are the exact
	// prefixes niedziela.pl's scraped headings carry, used by
	// render.LocalizeHeading to recognise and swap the label word while
	// keeping the citation untouched.
