Module quarto_divs 

Quarto div and callout block detection utilities

This module provides detection for Quarto/Pandoc fenced div syntax which uses ::: markers to create structured content blocks.

Common patterns:

• ::: {.callout-note} - Callout block with type
• ::: {.callout-warning} - Warning callout
• ::: {#myid .class} - Generic div with id and class
• ::: myclass - Simple div with class (shorthand)
• ::: - Closing marker

Callout types: callout-note, callout-warning, callout-tip, callout-important, callout-caution
