/* Site nav — one stylesheet for every static marketing page.
 *
 * Everything is scoped under .dsd-nav so it never collides with the per-page
 * .nav rules those pages already carry inline. The markup is stamped INTO each
 * page by scripts/seo/stamp-nav.mjs rather than injected at runtime: nav links
 * are internal links, and this site's whole problem is pages Google has never
 * crawled — JS-injected links would be exactly the wrong trade.
 *
 * .dsd-drawer is display:contents on desktop, so the menu and the auth pair lay
 * out as if they were direct flex children of the nav; on mobile it becomes the
 * single collapsing panel that holds both. One wrapper, no duplicated markup.
