// colitur ordo booklet -- Typst. flavour: typst
// Build: colitur table --year 2027 --template ordo.typ > ordo.typ && typst compile ordo.typ
//
// ONE compile pass, not two: Typst resolves its own table of contents (built
// from headings via the outline function below) and every page number it
// shows internally, inside a single invocation -- there is no LaTeX-style
// pageref/aux-file dance and no "run it twice so the numbers settle". That is
// a genuine advantage of this flavour over ordo.tex, not merely a different
// syntax for the same thing.
//
// A5, CONTINUOUS (Defect 2): no forced page break per week any more --
// see ordo.tex's own header for the measured "why" (a full 7-day week
// already fills most of an A5 page even tightened, so the real saving
// comes from the year's many SHORT boundary weeks no longer wasting a
// whole page each). Every fixed string (headings, the Epistle/Gospel/
// Commemoration/Week labels) comes from the view's term vocabulary rather
// than being written into this file, so a translated booklet needs no
// template edit -- only a different --lang. Same discipline as ordo.tex;
// see that file's own header for the full reasoning, repeated only where
// Typst changes it below.
//
// The observed day's own display name is a PLAIN resolved string
// (View.of_days), never a lang-keyed object, exactly as in every other
// shipped flavour -- there is no dotted-la-with-slug-fallback idiom to
// write here at all.
//
// The engine has no parent-path syntax: nested inside a month's own week
// loop, a bare week-number reference finds the WEEK's own number, and there
// is no way to reach the enclosing month's from there. That is why each
// week object carries its own month number, month name and abbreviated
// month name fields (lib/render/view.ml), used below via month_name/
// month_num/month_abbr instead of a parent-path reference the engine
// cannot express. The same view resolves the week's own Roman numeral too
// (num_roman, arabic num kept alongside it for a tradition that wants it),
// the day-of-month of its first and last in-month day (first_dom/
// last_dom), and single_day (true for a one-day week) -- the punctuation
// choice between Ian 1 and Ian 1-2 this logic-less engine cannot make for
// itself, so the heading below picks the dash only inside an inverted
// single_day section.
//
// The engine also rejects an empty tag path outright (a bare-dot section or
// variable is a parse error, not an invented "current context" behaviour),
// so every loop below names a field on the object it walks rather than
// trying to interpolate the object itself.
//
// This template's own line comments are plain text to the engine: it has no
// awareness of Typst's // syntax, and a stray double-brace pair inside one
// would still be parsed as a tag -- which is why this whole header, like
// ordo.tex's own, is written without ever typing two curly braces next to
// each other, even to name a field.
//
// One TOC level, not two: LaTeX's own ordo.tex prints the month name ONCE
// per month with its weeks dotted-and-paginated underneath, because it
// walks the months-then-weeks nesting directly in its own hand-built TOC
// loop. Typst's outline instead builds its table of contents automatically
// from real document headings, so this stays a flat list of week headings
// rather than being restructured into two heading levels -- changing
// outline depth/structure is a bigger, riskier change than this defect
// calls for. Each heading is the week's own Roman numeral plus the span
// of in-month dates it covers (e.g. Hebdomada I (Ian 1-2)), with no month
// name repeated -- the month heading below is a separate, non-heading
// BANNER (not part of the outline) that already establishes it once per
// month. Defect 2 DID add a "is this the month's first week"
// flag to the view model (lib/render/view.ml's own [first], the same
// "cheap flag beats invented template logic" call [last] already made
// elsewhere) -- used below for a separate, non-heading month BANNER
// printed just above that first week's own heading, not by restructuring
// the heading/outline itself. The banner's own sticky:true (separate from
// the heading show-rule's below) is needed for the identical reason: an
// early draft without it put "Aprilis 2027" alone at the very bottom of
// a page with the entire month below it on the next one -- not caught by
// a check for an orphaned HEADING (a banner is not one), only found by
// looking at the rendered page. Chaining two sticky blocks keeps
// banner+heading+first day box moving together.
//
// Each day box is tightened from an earlier draft (0.6mm inset, 0.42em
// leading, 7pt meta text on its own separate rank/colour line) for this
// same continuous flow -- see ordo.tex's own header for the measured
// reasoning, identical here: a full week already fills most of a page,
// so folding rank/colour onto the SAME line as the citations (this box
// is far wider than it is tall) is what buys back a second week's worth
// of room, not the font/inset trim alone.
//
// Colour swatch: the six colour names this rite emits (white, red, green,
// violet, rose, black -- Colour.to_string's own closed vocabulary) are used
// as literal dictionary keys inside a Typst string argument below, the same
// trick ordo.tex's own \swatch{licol...} macro-name concatenation relies
// on. Both templates depend on that vocabulary staying plain lowercase
// ASCII words with no markup metacharacter in it; the escaper still runs
// over the substituted value regardless; a value outside that closed set
// would need a different placement, not a different escaper.
