/* landing-shared.css -------------------------------------------------------
   Shared with the in-app landing at gdbs.getvaultsync.com. Copied verbatim
   from core/GdbsWeb.Api/wwwroot/css/app.css (lines ~1319-1610) so the
   marketing surface at getvaultsync.com renders with the same nav, hero,
   button, section, feature, domain, tier, faq, and footer primitives.

   Requires flux/flux.css + theme-bridge.css loaded first so legacy
   variables (--bg, --bg-alt, --bg-panel, --bg-hover, --bg-input, --border,
   --border-light, --text, --text-bright, --text-dim, --accent) all resolve
   off the flux design tokens for the chosen data-theme.

   covers most; these two are referenced by faq + free sections). */
