/* ============================================================
   Said Rustom — Portfolio
   Design system: dark, precise, high-contrast
   ------------------------------------------------------------
   Tweak defaults locked in production:
     · Mood    = Vault   (dark navy + blue accent)
     · Density = Compact (tight spacing scale, see --section-pad etc)
     · Texture = Grid    (blueprint background, see --bg-pattern)
     · Accent  = #3b82f6
   The mood/density/texture/accent panel is intentionally NOT
   shipped. Every value below is a CSS variable so any of these
   can be re-tuned in one place. See THEME-SYSTEM.md.
