/* Img.vision Marketing Site Sections: section menu
 *
 * [imgv_section_nav] sits in the sidebar column of the article and category
 * templates. From 1024px up that column is a sticky sidebar. Folded, it fits the
 * window; when an opened section makes it taller, the sidebar scrolls on its own
 * (thin scrollbar) so every link stays reachable.
 * Below 1024px the column moves above the article and shows only a breadcrumb
 * bar with a button; the tree becomes a drawer from the right, a popover
 * element, so there is no script. Colours and the typeface come from the
 * Spectra One child theme presets, with the same values as fallbacks.
