/* Floating pill-shaped top navigation bar.
 * Loaded by both the static landing/marketing pages (StaticPageLayout.hbs)
 * and the SPA shell (IndexPage.hbs) so the topbar stays visually identical
 * across worlds. Tokens are read from each world's :root — the SPA's
 * tokens.scss aliases --color-ink* / --color-muted to its --color-base-contrast*
 * scale so this file works in both. */
