/* ==========================================================================
   SOLON — marketing layer on top of the shared design system (web3.css).

   web3.css owns the tokens, the chrome and the product components; this file
   only adds the pieces the SOLON story pages need: the connection network,
   the value loop, the statement bands and the narrative grids.

   Everything here reuses the existing tokens, so the two files stay one
   visual system: deep blue-black surfaces, glass cards, soft glow, and
   motion that always reads as "connection".
