Catch up on the three rapid releases that reshape Subspace Builder with a tag hub, refreshed navigation, and a data-driven projects page.

For the longest time, sharing code from GitHub meant screenshotting or pasting raw snippets into Markdown. Both options felt brittle—screenshots hide the text from RSS readers, while copy-pastes drift out of sync the minute the upstream file changes. I wanted the readability of Emgithub, the SEO of server-side rendering, and zero third-party JavaScript.

That mix finally landed this week: a {% github %} shortcode that fetches code at build time, highlights it, numbers each line, and offers a copy button. All it needs is the GitHub blob URL and an optional style flag for light or dark chrome.

`ELEVENTY_ENV` is now wired into every npm script so drafts stay private in production while remaining easy to preview.

Walking through the fixes that led us from stretched screenshots to a lean Eleventy Img pipeline, plus a quick primer on how responsive image markup really works.

Adding Markdown-driven tables of contents means fewer manual edits, consistent anchors, and faster publishing all around.

I’ve always loved how iMessage or WhatsApp automatically turn a shared link into a little postcard. Until this week, that magic felt like a black box. I suspected there had to be an open standard behind it, but I’d never hooked it up myself. Cue a pairing session with GPT-5 Codex, and about two hours later, the 11ty Subspace Builder can mint its own branded previews for every post.

Here is an example card for this blog post.

Our first stable launch brings a polished Eleventy 3 starter with theme switching, accessible navigation, OG image automation, and a streamlined authoring flow.
