Type specimen

This page exists to be looked at, not read. It exercises every element the templates render, so a change to sass/style.scss can be checked against one page instead of against a memory of what the site used to look like.

The palette is Bonfire, committed in the Thylacine tree at docs/UTOPIA-VISUAL.md §1. Its background is #0e0c0c – not red, not warm grey, but near-black with a barely perceptible red cast, the way darkness looks when a fire a few hundred metres away cannot illuminate anything and only shifts the colour temperature of the air.

Prose

Body text is fg, #e4ddd8. Emphasis and strong carry the usual weight. Inline code such as burrow_attach sits on the lifted surface tone. Links look like this and underline on hover.

A blockquote takes the ember rule on its left edge. The shell yields commands to the kernel; every invocation is a derivation, which is what the mark means.

Footnotes work and land at the bottom of the article.¹

A third-level heading

Every heading gets an anchor link, so a paragraph deep in a long article stays addressable. Hover a heading to see it.

1. Ordered lists number themselves.
2. And nest:
   • like this,
   • and this.

Code

Highlighting comes from a Bonfire theme in extra/bonfire.json, rendered as CSS classes rather than inline styles. The colours are the committed palette, so a code block here and the same code in nora are the same colours – not an approximation of them.

        let tag = self.ring.submit(Op::Present { rect, slot: self.slot })?;
        loop {
            match self.ring.reap()? {
                Some(cqe) if cqe.tag == tag => break,
                Some(cqe) => self.pending.push(cqe),
                None => continue,
            }
        }
        self.slot = (self.slot + 1) % self.slots;
        Ok(())
    }
}

A block with no language declared falls back to plain text:

Tables

Wide tables scroll inside their own container rather than pushing the page sideways.
