+/// Configure the template for a KTU paper.
+/// - font (str): Text font to use for the paper.
+/// - figureNumberingPerSection (bool): Whether to number figures per section rather than globally.
+/// - uppercaseSectionTitles (bool): Whether to uppercase section titles.
+/// - unnumberedHeadingAlignment (alignment): Alignment for unnumbered headings.
+/// - figureKinds (dictionary): Extra figure kinds, e.g.
+///   `(command: (supplement: "komanda", ref-name: "komanda", single-name: "komanda"))`.
+///   Use them with `figure(kind: "command", ...)`. Keys:
+///   - `supplement` (required): text after the number in captions, e.g. "1 komanda.".
+///   - `ref-name`: text used in references, e.g. "(žr. 1 komanda)". Defaults to `supplement`.
+///     Can also be a function `count => string`, called with the number of elements
+///     referenced together, for kinds whose wording depends on it, e.g.
+///     `count => if count == 1 { "komandą" } else { "komandas" }`.
+///   - `single-name`: full word used when the figure is the only one of its kind
+///     and is left unnumbered, e.g. "Komanda." and "(žr. komanda)". Defaults to `supplement`.
+///     Currently only tables and images are left unnumbered when single, so this only matters for kinds added there.
+/// - figureLayout (dictionary): Page-break behaviour and caption position per figure kind,
+///   `(kind: (breakable: bool, caption: top | bottom))`, every field optional. Kinds are
+///   `table`, `image`, `raw` (code), or a key of `figureKinds`. Defaults: `table` and `raw`
+///   are breakable; everything else is unbreakable. Example: `(raw: (breakable: false, caption: bottom))`.
+///   A breakable figure's top caption stays attached to the start of the body.
+///   Use `breakable-figures[...]` / `unbreakable-figures[...]` to override it locally.
+/// - code (dictionary | none): Code block configuration, or `none` to leave raw blocks unstyled. Keys:
+///   - `font` (str): Monospace font. Defaults to "Hack".
+///   - `spacing` (relative): Word spacing of code text. Defaults to `80%`.
+///   - `fill` (paint): Background of code lines. Defaults to `white`.
+///   - `stroke` (stroke | none): Outline around the code block. Defaults to `0.5pt + black`; `none` removes it.
+///   - `numbers` (bool): Show line numbers. Defaults to `true`.
+///   - `radius` (length): Corner radius of the outline. Defaults to `0pt` (square corners).
+///   - `display-name` (bool): Show the language name badge. Defaults to `false`.
+///   - `display-icon` (bool): Show the language icon badge. Defaults to `false`.

+== Formulės
+Formules galima išreikšti eilutėje, pavyzdžiui $E = m c^2$ arba atskiroje eilutėje, pavyzdžiui:
+$
+  E = m c^2
+$ <formula-label>
+
+// TODO: fix
+Formulės atskiroje eilutėje numeruojamos besąlygiškai, galima gauti formulės numerį #ref-no(<formula-label>) arba visą formulės nuorodą #custom-ref(<formula-label>).
+
+== Kodo fragmentai
+Kodo fragmentus galima išreikšti eilutėje, pavyzdžiui `print("Hello, world!")` arba atskiroje eilutėje, pavyzdžiui:
+#figure(```python
+def main():
+  print("Hello, world!")
+if __name__ == "__main__":
+  main()
+```, caption: [
+  Python kodas
+]) <code-label>
+
+Galima gauti kodo fragmento numerį #ref-no(<code-label>) arba visą kodo fragmento nuorodą #custom-ref(<code-label>).
+
+== Naudotojo apibrėžtos figūros
+
+Naudotojai tai pat gali apibrėžti savo figūras, pavyzdžiui, komandų fragmentus. Pavyzdžiui, galima apibrėžti komandų fragmentą su papildoma informacija ir naudoti jį dokumente. Galima gauti kodo fragmento numerį #ref-no(<custom-figure-label>) arba visą kodo fragmento nuorodą #custom-ref(<custom-figure-label>).
