/* ==========================================================================
   Prologue section layout
   --------------------------------------------------------------------------
   The site is structured around the html5up.net "Prologue" template:
   four top-level sections (Intro, Portfolio, About Me, Contact) plus
   Blog. The styles below define how those sections render inside the
   existing cyber/technical shell. They intentionally reuse existing
   tokens (--neon, --cyan, --line, --bg-panel, etc.) so the cyber
   aesthetic stays consistent.
