/* ==========================================================================
   CODEBARREL IGNITE 1 — GLOBAL STYLESHEET
   ==========================================================================
   Purpose:
   Defines the visual design system, reusable UI styles, page sections,
   responsive layouts, animations, and accessibility preferences.

   Design direction:
   - Dark green and emerald accents for the brand identity.
   - Ivory backgrounds for readable content sections.
   - Monospace typography for technical labels and code-related UI.
   - Responsive layouts for desktop, tablet, and mobile devices.

   Maintenance note:
   Keep shared design tokens in :root so colors and fonts can be updated
   consistently across the entire website.
