/*
 * Kenyon 1: its announcement on the home page (index.html, .launch) and its own page (kenyon.html), since
 * 10 November 2026 (the owner: "have a big announcement thing on elovaren website", with Anthropic's announcement
 * of a model as the example: one wide picture with the name large on it and a way on, and a dark page behind it
 * with the date, the name, the picture, a list of the page's parts and then the parts). The layout, the words and
 * the picture are Elovaren's own. The picture is not an illustration: it is one flinch of Kenyon 1's nervous
 * system, as it was recorded (img/kenyon, tools/kenyon-film). The film's frame and its two round buttons are the
 * site's own (style.css, .film-frame and .film-controls); kenyon.js runs them.
