Content can be wrapped in `@@`double at signs`@@` to apply specified CSS styles or classes to it. There are multiple ways to use this syntax, as presented below.
Inline content wrapped in `@@`double at signs`@@` without specifying style or class will be assigned the `.tc-inline-style` and displayed as highlighted text. The foreground and background colours of the highlighted text are defined as `highlight-background` and `highlight-foreground` in the current palette.
