EMPHASIS · IN ORDER OF PREFERENCE

1 colour → an accent run

2 inversion → a filled run

3 block prefix → █ a marked line

4 UPPERCASE + TRACKING

! NEVER

Bold: the font has one weight and browsers fake it badly

Sizes off the 11px grid: 14, 18 and 24 blur the pixels

Uppercase on a heading or a sentence

A second typeface, anywhere

CodeBlock

One block element per line. A collapsed code block is the worst failure this design can have. Full-bleed on mobile.

A fenced code block in a post's markdown goes through a different path. The rehype plugin in src/lib/rehype-code-block.ts builds the same header-and-line anatomy from Shiki's output, with no React involved. See it live on a real post.

Callout

Dashed border is what tells it apart from every other box. Keep it dashed.

content/Callout.astro

! NOTE

Ratios on this page are computed against --color-surface-window at build time. Change the token in theme.css and every ratio on this page moves with it.

! WARN

If a specimen here ever disagrees with the real component, the specimen is wrong. This page is generated from the same code the rest of the site imports.

BookCover

2:3. Reading stays full opacity with an accent border; finished dims to 80%. No cover falls back to a dither placeholder.

AsciiBanner

Decorative block texture set as text, never drawn letterforms. `aria-hidden`. `sweep` is used once, on the 404.

Outline

A post's table of contents. `rail` is the sticky desktop column; `disclosure` is the bordered `<details>` on narrow screens.

content/Outline.astro

OUTLINE

Prose

Wraps rendered markdown. Caps at 68ch. `##`/`###` prefixes come from CSS, not the source text.

content/Prose.astro

The frame

A paragraph looks like this, capped at measure so a line never runs too wide to read.

List markers are an en dash, not a bullet glyph
Inline code reads as a value you'd copy

A blockquote takes a left accent rule instead of a border box.

Window · TabBar · Scanlines

The frame, the tab strip, and the ambient overlay. Not re-rendered here. This page is already inside one.

chrome/

The chrome bar above carries this page's own title and the 12 COMPONENTS count; the tab strip below it is highlighting system/ right now. Squares, never circles. The third one is the accent.
