/*
 * Visually hides the agent-facing llms.txt discovery directive rendered by
 * '_templates/header.html'.
 *
 * The Agent-Friendly Docs spec (https://agentdocsspec.com/spec/) requires the
 * directive to be present in the served HTML so agents can discover llms.txt
 * and the Markdown variants of each page.  'display: none' would remove it from
 * the accessibility tree and risk it being treated as cloaked content, so the
 * standard clip-rect technique is used instead: the element stays in the DOM and
 * in the accessibility tree, but occupies no visible space.
