/* ============================================================
   TRUSTGUARD SERVICES — DESIGN TOKENS
   Palette: brand red pulled from client mockups (#C42121),
   deep ink/steel darks (not flat black — a cold blue-black,
   like CCTV monitor glow), warm paper off-white, and a
   hi-vis accent lifted from the guards' own vests — a nod to
   the one colour that's actually on-site every day.
