/*
 * Page "Méthode" (ticket 0237, sub-lot B2-d, rules 21 and 22): the style of this page alone,
 * loaded by templates/core/method.html after tokens.css and site.css. The free design of
 * direction D (docs/design/direction-2026-10/d/) has no page for it: it takes its language,
 * that of the head of a page and of the numbered sections of the preview (`.page-head`,
 * `.ov-section`), the rows ruled in Encre of its catalogue (`.catalogue`, `.row`).
 *
 * Every colour is a variable of tokens.css (nothing is written here); no movement, no
 * gradient, no shadow: the closed lists of apps/core/tests/test_design_components.py stay
 * those of site.css. The fade of the sections at their arrival is the class `.reveal` of
 * static/css/site.css (rule 20 (e)), set by the comfort script, never required.
