/*! longread.css v0.1.1 | MIT License | https://github.com/ktakahashi74/longread.css
 *
 * Reading CSS for essays, papers and long posts on screen, in many
 * languages and scripts.
 *
 * Contract: put class="longread" on the element that contains the prose,
 * give it (and any nested passage in another language) a correct lang
 * attribute, and add dir where the direction is not left to right.
 * Ordinary prose needs no other classes. Footnotes may come from pandoc
 * (role="doc-noteref" etc.) or from GFM (data-footnote-ref etc.).
 *
 * The file has no colour palette: decorative rules, borders and
 * backgrounds are derived from the text colour. It is unlayered, and every
 * rule has the specificity of one class (.longread :where(…) or
 * .longread:where(…)), apart from the two ::marker rules, which add a
 * pseudo-element. Element-level resets therefore lose to it, and a later
 * rule with a class in the same layer wins over it. To place it in a
 * cascade layer, import it with @import url("longread.css") layer(longread);
 *
 * Order: 1 defaults, 2 element styles, 3 typesetting by language,
 * 4 exceptions that must win over 3, 5 spacing at the edges.
