/* wesbecher.llc · global navigation
 * Shared chrome across /, /playbook, /pmf and /capacity. Self-contained: it
 * depends on no route's tokens, so the four pages stay independently servable.
 * Each page sets --gnav-w and --gnav-pad to match its own container so the
 * brand lines up with the content beneath it.
 * The drawer is a <details> element: it opens and closes with no JS.
