/* Project-specific overrides, loaded after the shared o6 theme. */

/*
 * Nav items that sit at section level but are single pages.
 *
 * With "navigation.sections", the first level below a tab renders its groups as
 * bold section headings (Material does this from 76.25em, the o6 theme in the
 * 64em-76.23em band). A single page at that same level -- Manual > Node API,
 * Manual > Performance -- stays an ordinary link and reads as a child of the
 * section above it rather than as its peer.
 *
 * The ":has()" test is what keeps this honest: only a list that actually
 * contains section headings gets its plain items promoted. Lists with no
 * sections at all -- o6\Python > Install, Commercial build -- are left alone,
 * since there is no heading level there to match. Below 64em the drawer does
 * not bold sections either, so neither do we.
