/* ===========================================================================
 * The reading plan — the scripture section's colour, and a course's furniture
 * ===========================================================================
 *
 * Two pages load this file: index.html, the plan's front door, and track.html,
 * one track read as a course. They are one section of the site and therefore
 * one colour, so the palette is declared once here rather than twice.
 *
 * The site gives every section a liturgical colour, and scripture is GOLD.
 * Published, that colour is not declared here at all: the site's layout marks
 * the reading area `section-toned section-gold` and the values arrive from the
 * site's own stylesheet, so retuning the section there carries here by itself.
 *
 * THE GOLD ACCENT IS NOT A TEXT COLOUR. #b07c07 on white is 3.66:1 — under the
 * 4.5:1 that body text needs. Everything set in the section colour is set in
 * --section-ink (#7e5802: 6.39:1 on white, 6.13:1 on the page, 5.10:1 on the
 * toned row it is used against); --section-accent is for rules, borders,
 * markers and fills, where contrast is a matter of visibility rather than
 * legibility. Those figures are measured on the values `site.css` ships, which
 * is now the only place they are written; nothing here restates them.
 *
 * LEGIBILITY GOVERNS. The scripture is the point and the apparatus is not:
 * every measure is capped at --measure, the passage keeps the shared file's
 * generous leading, and nothing in the apparatus is set larger or darker than
 * the verse it sits beside.
 * ======================================================================== */
