/* Landing page (v2 design system — redesign R2)
   Marketing homepage at root ("/").

   Consumes only semantic DS tokens defined in tokens.css. No --pico-*
   references, no hex literals, no raw spacing/typography literals.

   Section selectors map 1:1 to the four-section editorial layout the
   home view renders: hero · constat (I) · changement (II) · dossier
   (III) · securite (IV) · cta · foot. Each block consumes one BEM
   namespace; no shared selectors between sections.

   The legacy `.landing-*` block at the bottom is still consumed by
   app/views/layouts/devise.html.erb (logo height + wordmark sizing).
   Keep until devise switches to .foot__brand / .lc-topbar__brand.
