/* Fractales Ventures — site styles
   Layout concept: an editorial ledger on warm ivory. Fine indigo "veins" connect
   ideas the way the dragonfly's wings branch; asymmetric two-column sections,
   generous margins, hairline rules with small open nodes taken from the banner.
   Single light theme by design: the brand artwork is ivory, so the site keeps it. */
