DESIGN PLAN (v2 — editorial government-portal rebuild)
--------------------------------------------------------
Subject: a trustworthy, editorial government-exam information portal.
Restrained, professional, no SaaS gloss — clear hierarchy, real contrast,
minimal decoration. System font stack only (no third-party font request).

Color tokens (fixed per brief):
  --primary       #123b63  deep blue — headings, primary UI, links
  --primary-dark  #0b2946  hover/active state of primary
  --accent        #f59e0b  amber — CTAs, highlights, status flags
  --success       #15803d  confirmed/open status
  --danger        #dc2626  urgent/closed status, warning notices
  --text          #172033  body text
  --muted         #64748b  secondary text
  --background    #f8fafc  page background
  --surface       #ffffff  card/panel background
  --border        #e2e8f0  hairline borders

Principles: no gradients, no heavy shadows, minimal border-radius, status
conveyed with shape + text (never colour alone), motion limited to menu/
accordion interactions. Single system font stack for performance.
