Today I've updated the blog's typography system, migrating from a dual-font approach to Google Fonts Commissioner. This change brings a more unified visual identity while maintaining the readability improvements from the recent typography scaling updates.

Commissioner is a low-contrast humanist sans-serif with almost classical proportions, designed as a variable font. What makes it particularly appealing is its versatility — the variable weight axis allows smooth transitions from 100 to 900, though I'm using a focused range of 400-700 for optimal web performance. The humanist design provides excellent readability for extended reading sessions, while the variable weights give precise control over text hierarchy.

The previous system used Work Sans for body text and Montserrat for headings, which worked well but required loading two separate font families. By consolidating to Commissioner, I've reduced the number of font files while gaining more flexibility through the variable font technology. Body text renders at weight 400, while headings use weight 600, creating clear visual distinction without the need for separate typefaces.

Importantly, this update preserves all the responsive typography improvements implemented yesterday. The fluid clamp() scaling continues to ensure that headings guide rather than dominate, with smooth size transitions across all viewport widths. Commissioner's character fits naturally into these proportions, maintaining the balanced visual hierarchy that makes the content comfortable to read on any device.

From a technical perspective, the implementation uses Google Fonts' CSS API with automatic font-display: swap for optimal loading performance. The variable font format means a single WOFF2 file can handle all weight variations, reducing total download size compared to loading multiple static font files. This efficiency gain becomes more significant as the blog continues to grow.
