Replaces the single-font setup with a three-font system optimized for technical content: Space Grotesk for headings, Inter for body text, and JetBrains Mono for code blocks.

Changes:

  • app/layout.tsx: Import and configure three fonts with dedicated CSS variables

    • --font-heading → Space Grotesk
    • --font-body → Inter
    • --font-code → JetBrains Mono

  • css/tailwind.css: Wire up font variables to semantic uses

    • Map --font-sans to --font-body for default text
    • Add --font-mono mapped to --font-code for code blocks
    • Apply --font-heading to all heading elements (h1-h6)
const spaceGrotesk = Space_Grotesk({ 
  subsets: ['latin'], 
  variable: '--font-heading' 
})
const inter = Inter({ 
  subsets: ['latin'], 
  variable: '--font-body' 
})
const jetbrainsMono = JetBrains_Mono({ 
  subsets: ['latin'], 
  variable: '--font-code' 
})
--font-sans: var(--font-body), ui-sans-serif, system-ui, sans-serif;
--font-mono: var(--font-code), ui-monospace, 'Cascadia Code', Menlo, Consolas;

:where(h1, h2, h3, h4, h5, h6) {
  font-family: var(--font-heading), ui-sans-serif, system-ui, sans-serif;
}

Option 1: The "Terminal" Aesthetic (Best fit for your brand)
This pair gives your site a distinct "CLI / Coding" vibe without sacrificing readability for long blog posts.

Headings: Space Grotesk (A quirky, geometric sans that feels "techy")

Body: Inter (Standard, highly legible) or Space Mono (If you want to go full hacker, though it can be harder to read in long paragraphs)

Code Blocks: JetBrains Mono (The gold standard for code)

import { Space_Grotesk, Inter, JetBrains_Mono } from 'next/font/google'

const spaceGrotesk = Space_Grotesk({ subsets: ['latin'], variable: '--font-heading' })
const inter = Inter({ subsets: ['latin'], variable: '--font-body' })
const jetbrains = JetBrains_Mono({ subsets: ['latin'], variable: '--font-code' })

Walkthrough

This pull request implements a multi-font typography system replacing a single-font approach. Font configuration now uses Space Grotesk for headings, Inter for body text, and JetBrains Mono for code blocks, with corresponding CSS variables added to Tailwind's theme configuration.

Changes

Cohort / File(s) Summary
Font imports and layout configuration
app/layout.tsx		 Added Inter and JetBrains_Mono font imports; renamed spaceGrotesk constant and updated CSS variable to --font-heading; introduced inter and jetbrainsMono font configurations with --font-body and --font-code variables respectively; applied all three font variables to root element className.
Tailwind theme and utilities
css/tailwind.css		 Updated --font-sans CSS variable from var(--font-space-grotesk) to var(--font-body); added new --font-mono CSS variable with fallback stack; introduced new utilities rule applying --font-heading to all heading elements (h1–h6).

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~5 minutes

  • Straightforward configuration changes following a consistent pattern across two files
  • No logic modifications or control flow alterations
  • Font import syntax and CSS variable mappings are standard and well-established

Poem

🐰 Three fonts hop into view, ✨
Space Grotesk leads the heading crew,
Inter flows smooth for bodies true,
JetBrains Mono codes debut! 🖤

🧹 Nitpick comments (1)
app/layout.tsx (1)

15-31: Font configurations are properly structured.

Each font is correctly configured with:

  • subsets: ['latin'] for appropriate character coverage
  • display: 'swap' to prevent flash of invisible text
  • Semantic CSS variable names that match tailwind.css mappings

Note that loading three custom fonts will increase initial page weight. Consider monitoring Core Web Vitals (LCP, CLS) to ensure acceptable performance.

🔇 Additional comments (4)
css/tailwind.css (2)

10-13: Font variable mappings are well-structured.

The font variable chain correctly references --font-body for sans-serif and --font-code for monospace, with appropriate system font fallbacks. This properly integrates with the font definitions in app/layout.tsx.

84-87: Global heading font application looks correct.

The :where() selector applies Space Grotesk to all headings with zero specificity, making it easy to override when needed. This matches the PR objective to use Space Grotesk for headings.

app/layout.tsx (2)

5-5: Font imports are correct.

All three Google Fonts are properly imported using the Next.js font API, which optimizes font loading and prevents layout shift.

79-79: Font configuration is correctly implemented and requires no changes.

The fonts are properly configured using next/font/google with the display: 'swap' property on all three fonts (Space_Grotesk, Inter, and JetBrains_Mono). Next.js automatically downloads and self-hosts these fonts at build time, serving them as static assets in production—there is no runtime dependency on the Google Fonts CDN. The font CSS variables (--font-heading, --font-body, --font-code) are correctly applied to the HTML element and used throughout the stylesheet with appropriate fallbacks.
