/* =====================================================================
   VergeDefence — Design System
   Layout faithful to a top security-research firm's site (Trail of Bits):
   • fixed dark left rail: logo, theme toggle, ICON+LABEL nav, contact CTA
   • sticky top bar: breadcrumb + search + stats
   • hero LEFT / featured research RIGHT (2-col)
   • squared neutral buttons w/ separate arrow box; red used only as accent
   • dithered (halftone-masked) service icons, mono/uppercase eyebrows
   Original code, copy, and assets.
