   landing.css — the marketing landing page shown at "/" for logged-out users.
   Ported from the standalone bases/webapp/resources/public/landing.html (#7).

   EVERYTHING is scoped under `.landing-root` so the bespoke editorial look (its
   own palette, type, full-bleed layout) cannot leak into the dark-themed app —
   several class names (.feature, .system, .masthead, .label) collide with app
   CSS, so the wrapper scope is load-bearing. The landing brings its own colour
   tokens (--lp-*) and does not touch the app's design tokens.
