Markdown now supports stylized callouts for notes, warnings, and tips

You can now embed callout blocks directly in your markdown content, and they'll render as proper styled boxes with icons.

Supported types:

• Note — neutral context the reader should pay attention to.
• Info — additional information that complements the main flow.
• Warning — heads-up about a pitfall or consequence.
• Danger — high-stakes warning the reader cannot afford to miss.
• Success — confirm a step or highlight a positive outcome.

Each type gets a context-appropriate icon and color theming that works in both light and dark mode. If you write technical content or guides, this is a substantial readability upgrade — readers can scan callouts at a glance and pull out the structure of a long piece much faster.
