{#- Full override (sphinx_rtd_theme/layout.html does a plain {% include "searchbox.html" %},
   not a named block, so there is nothing to {% extends %} + {% block %} here). Only mounts
   the Pagefind UI on CF-Workers builds (conf.py sets html_context['vyos_cf_build'] from
   DOCS_VERSION_SLUG) — ReadTheDocs runs plain Sphinx with no Pagefind step, so the mount's
   assets would 404 there. On RTD (and any other non-CF build) fall through to the theme's
   stock server-side search form via Sphinx's "!" bang-prefix (forces resolution from the
   theme, bypassing this override, per sphinx/jinja2glue.py). #}
