Includes

Split long presentations into multiple files with !include():

!include(path/of/sdf or md file)

You can include a directory — files are included alphabetically and recursively:

!include(path/of/directory)

Subdirectories are walked automatically; the slide order follows the alphabetical sort at every level:

slides/
├── 01-intro.md
├── 02-demo.md
├── 03-advanced/
│   ├── 01-feature-a.md
│   ├── 02-feature-b.md
│   └── 03-feature-c.md
└── 99-questions.md

!include(slides)

→ slides appear in the order shown above (01-intro, 02-demo, 03-advanced/01-feature-a, 03-advanced/02-feature-b, 03-advanced/03-feature-c, 99-questions).
