/* =========================================================================
   SYLC — Senergy Young Leaders Club
   Layout concept: "the open ring". The Senergy mark is a ring left open on
   one side; sections open with that arc as their marker, the hero assembles
   the ring over a living teal cloud, and content sits in a left-aligned
   editorial grid. Dark-first, single look (the cloud owns the hero).
   Palette sampled from the Senergy logo: deep teal #004755 -> teal #00A99D.
