# 02-typography.ts All Monospace

export typography()

Every single character rendered in monospace. Three font families, one philosophy.

'JetBrains Mono' // display & headings
'IBM Plex Mono' // body text & UI
'Fira Code' // code blocks & data

// Display — JetBrains Mono 800 2.8rem / 1.1

const design = "code";

// Heading 1 — JetBrains Mono 700 2rem / 1.2

Every pixel speaks monospace

// Heading 2 — JetBrains Mono 600 1.5rem / 1.3

Systems built on fixed-width grids

// Heading 3 — JetBrains Mono 600 1.15rem / 1.4

Where readability meets engineering

// Body — IBM Plex Mono 400 0.93rem / 1.7

The developer aesthetic treats the code editor as a first-class design tool. Typography is monospaced, alignment is sacred, and every element follows the rigid grid of a terminal emulator. There is beauty in constraints. There is clarity in uniformity.

// Caption — Fira Code 300 0.75rem / 1.5
