/* =========================================================================
   TopBetting.co.ke — design system (Sprint 3, frozen)
   =========================================================================
   Direction (Foundation Lock 16): editorial, calm, trust-first. Serious
   consumer-finance publication, not a casino lobby. No neon, no gradients,
   no gold, no animation, no fake dashboard chrome.

   FROZEN DECISIONS (16.2 / 16.3 — change only by explicit unlock):
   - Trust accent: deep green  #14532D  (links, primary actions, structure).
   - Functional colours carry MEANING ONLY, always with a text label:
       verified/tested-pass  green  #15803D on #F0FDF4
       pending/unverified    amber  #92400E on #FFFBEB
       warning/failed        red    #B91C1C on #FEF2F2
   - Typography: system font stack (fastest, zero requests), 17px body on
     mobile, 1.6 line height, headings by weight/size, never colour.
   - Mobile-first at 360px; tables collapse to labelled stacked rows.
   ========================================================================= */
