Theme

Campfire uses a single Tailwind-based theme per deck: theme.css at the project root. Tailwind v4 is configured entirely in CSS — there is no tailwind.config.ts.

@import "tailwindcss";

@source "./slides";
@source "./layouts";
@source "./components";

@theme {
  --font-sans: Inter, sans-serif;
  --color-background: oklch(1 0 0);
  --color-foreground: oklch(0.15 0 0);
  --color-primary: oklch(0.55 0.2 260);
}

The @source directives tell Tailwind exactly which folders to scan for class names — deterministic regardless of where the dev server runs.

Responsibility map

theme.css            visual tokens
components/mdx.tsx   markdown typography
components/*         visual primitives
layouts/*            narrative structures
slides/*             content

The slide canvas uses --color-background / --color-foreground as its base colors and --font-sans as its base typeface, so dark decks and custom fonts are one token away.

Multiple switchable themes are intentionally out of scope for v1.
