/* ==========================================================================
   Power Essence — "facet" design system

   Everything here derives from the logo: a person resolving into countable
   low-poly triangles, with pieces breaking off and drifting away. The palette
   is sampled directly from that artwork, including its ground: the mark's own
   shadow facets are deep indigo (#151451, #211A64), so the page is indigo
   rather than neutral black.

   The six spectrum stops are not decoration. Each one is a content theme, and
   they run in the mark's own left-to-right order.
