/* Zonative marketing site — August 2026 refresh.
   Ported directly from the app's unauthenticated landing page (app.zonative.com,
   src/ui/chrome/LandingPage.tsx + src/ui/styles.css) so zonative.com is
   recognizably the same dark, brand-native product experience rather than a
   separately-designed cream marketing page. Self-hosted fonts so CSP
   font-src 'self' is enough. Static site: no build step, no framework. */

   a real, size-appropriate gap after every heading tier without touching

/* At narrow phone widths the two status chips (BED-01/confirmed,

   edge without overlapping -- at 390px they overlapped horizontally by
   ~89px, with the right-hand chip drawn on top of and obscuring the left
   one. Below this breakpoint the two chips are offset both vertically
   and diagonally (overlay-a stays left-aligned but moves up to bottom:
   46px; overlay-b stays right-aligned at bottom: 12px), so there is no
   shared row for them to collide on regardless of exact rendered text
   width. Both chips stay inside the image's own darkened gradient band
   (bottom ~45%) so contrast is unchanged, stay fully inside the image
   bounds (no horizontal or vertical overflow), and both remain
   completely legible. No image pixels are touched -- this only
   repositions the HTML overlay chips. */
