Core Concepts
How content, navigation, configuration and theming fit together.
Tartarus has four moving parts. Understand these and the rest of the framework is predictable.
Content
How Markdown files map to pages, sections and navigation.
Navigation
Sidebar, breadcrumb, table of contents and page order — all generated.
Configuration
What belongs in hugo.toml, and why templates stay project-agnostic.
Theming
Design tokens, the light/dark/system switch, and how to restyle Tartarus.
