// Package liturgy parses the daily Catholic liturgy readings page into
// structured sections (1st reading, psalm, acclamation, gospel).
package liturgy

// Section is one reading section of the liturgy (e.g. "1. czytanie", "Psalm",
// "Aklamacja", "Ewangelia"): its heading, optional subtitle, the citation shown
// to the reader, an English-canonical lookup reference, a stable identifier for
// which liturgical part it is, and its body split into paragraphs of text lines.
//
// Citation is the display form (the reader's configured sigla dialect); Ref is
// the English-canonical reference the render resolves against a corpus. Keeping
// them apart lets the header read "Ps 27" in Polish sigla while the lookup uses
// "Psalms 27" (renumbered per Psalter). Ref is empty for sources that only
// carry a display citation; the render then falls back to Citation.

	Heading, Subtitle, Citation, Ref, PartID string

// modern niedziela.pl lectionary, English/Latin for the traditional
// missalemeum) -- never translated, like Section's own Heading/Citation.
// A source that carries no such data (or an unrecognised page/response
// shape) yields a zero DayInfo; callers must treat that as "omit the
// header", never as an error.

	// after Pentecost" (traditional); always "" for the modern lectionary,

	// "violet", "red", "rose", or "" when unknown/unmapped.
