/*
 * The article under the table, the "All 118 elements" table and the footer.
 *
 * Colours come from the theme tokens in css/ipt.css, so the article follows the
 * Light / Dark switch.
 *
 * Mediavine rule (CONTRACT.md): `article.ipt-article.entry-content` inside
 * `body.single-post` is Mediavine's content container, and it inserts units
 * between the TOP-LEVEL children. So:
 *  - the 720px measure lives on the article's own padding, never on the children,
 *    so injected ad containers get the same column;
 *  - children are styled by enumerated tags, `> :is(p, h2, h3, ul, ol, table,
 *    figure)`, never `> :not(...)`, which would also narrow the injected divs.
 * #ipt-all is a sibling of the article, outside `.entry-content`, so no ad lands in it.
