/* /contribute — "Как поучаствовать?" The community-invitation page: an
   inspiring address plus a clear, scannable map of every way to help. Reuses
   panels, buttons, badges and the FAQ <details> accordion; adds a hero with a
   gently animated "?" and two small schematics (the edit pipeline + the trust
   ladder). One blue accent, otherwise monochrome — hierarchy from type, weight
   and spacing, per the house style. */
