Built-in Components

Headings, paragraphs and lists carry most of a talk. This section covers the
pieces that aren't plain prose — the ones Tachyonn renders with a component of
its own.

They all share the same contract: you write a small amount of .tac, and the
renderer decides how it looks. Nothing here needs a plugin, a CDN, or an
internet connection — every one of them is bundled and works offline.

In this section

• Highlight Boxes — ### opens a titled box inside a slide.
  Standard, alert, example, or a variant you name yourself.

• Math — +[…] for inline and display LaTeX, rendered by
  KaTeX, with global macros you define once in the frontmatter.

• Other Components — Mermaid diagrams, Nerd Font icons, and
  /component[…] for embedding a real Vue component (a QR code, for instance).

Everything is offline

KaTeX, Shiki, Mermaid and the Symbols Nerd Font all ship inside Tachyonn. A
deck that uses every feature on these pages still renders on a laptop in a
lecture hall with the Wi-Fi off.
