/* =========================================================
   IndiaScamCheck.com — base design system
   =========================================================
   Palette rationale:
   - Deep ink-navy: authority/trust without going near-black-generic
   - Cool paper background: calmer than the cream/terracotta AI-default
   - Amber = caution/attention. Teal = verified/safe. Brick-red = emergency
     ONLY (reserved for scammed.html so it never loses urgency through overuse)
   Type rationale:
   - Lexend for body: designed to improve reading proficiency — a deliberate
     fit since this site is read by panicked and non-expert readers
   - Space Grotesk for display/labels/numbers: gives an "alert console" /
     instrument-panel feel appropriate to a safety-checking tool
