/*
  Project Result / Case Study Page Styles
  ----------------------------------------
  Shared across all /results/ case-study pages.
  Linked after tokens.css and styles.css.

  Color rule:
  - All values use tokens from assets/css/tokens.css
  - No hardcoded brand hex colors
  - Amber/accent used only for warnings, risk, and attention states
  - primary for trust and technical clarity
  - secondary for improvement and success states
