QuarryDeveloper tool site

Quarry is an Astro theme for a developer tool: a marketing site and a documentation site that share one grid. It moves both onto the discipline of a printed technical reference — what fills the screen is rules and numbers rather than cards and shadows.

How it reads

• Sections are numbered, and the number hangs in the left margin while the section scrolls, so a reader always knows where they are
• Density lives in one 38rem column: the hero, the pricing table and the documentation body are all the same width, so the typesetting does not break when a visitor crosses from marketing into the manual
• One accent colour carries the numbers, the current position and the focus ring, and nothing else is coloured
• Dark mode

What Pro adds

The documentation half on the same grid as the marketing site, with search and a changelog. See it at quarry.ondelva.com/docs.

Under the hood

• Static HTML with no client framework, 100 on Lighthouse
• A feed, and an AGENTS.md map for AI coding tools
