# Mono-led workbench — type pairing recipe

## The idea
- A monospace takes the lead in headings and labels to signal precision and craft, while a clear sans carries the explanations so reading never feels like reading code.

## Use it for
- Technical blogs and changelogs
- Developer product pages
- Maker and hardware project write-ups

## Avoid it when
- The audience is non-technical and could read it as cold
- Headings are long, since fixed-width letters take more room

## The faces
- Headings: JetBrains Mono (@fontsource/jetbrains-mono), weights 700
- Body: IBM Plex Sans (@fontsource/ibm-plex-sans), weights 400 and 600

## Scale and rhythm
- Scale: 13px, 15px, 18px, 22px, 28px, 36px
- Heading line height: 1.2
- Body line height: 1.65

## Principles
- Use the monospace for headings, labels, numbers and inline code; keep paragraphs in the sans.
- Keep the scale compact: monospace headings feel loud sooner than proportional ones.
- Line numbers, versions and dates read best in the monospace so their digits line up.
- Use the semibold sans for emphasis inside paragraphs rather than switching faces mid-sentence.
