feature: Timeline Open Graph images (subspace)

I’m really happy that I built the timeline feature into my blog, because it gives me an easy way to write about little moments and keep them somewhere permanent, platform agnostic, and accessible without any kind of paywall or login wall. The ProjectSpire SwiftUI card view WIP entry is exactly the kind of thing I wanted this for: a small progress record I can send to friends and family without needing it to be a full post or trapped inside a social feed.

I shipped dedicated archive index pages in v1.30.0 of 11ty-subspace-builder, including a timeline months index alongside the earlier weeks index. It also tightens up the shared archive navigation, which makes the timeline's growing set of month and week views feel more connected instead of like isolated pages.

I shipped a dedicated /timeline/weeks/ index in v1.29.0 of 11ty-subspace-builder. It groups both month-banded weeks and ISO calendar weeks by month, includes entry counts on each link, and makes the older week archive pages easier to browse without already knowing the exact week key.

I’m thinking about a timeline-specific tags page at /timeline/tags/<tag>/ so I can group related entries together and follow one topic across time without losing the chronological context. It would make the timeline feel a little more like a long-running notebook for a single idea instead of only a straight feed.

Shipped a fix for the timeline entry detail view in v1.27.1 of 11ty-subspace-builder. Earlier in thread now includes older siblings from the same branch and keeps the nearest prior entry closest to the current one instead of flipping the thread upside down.

I shipped month archive pages for timeline entries, month-banded week archive pages under /timeline/weeks/, and ISO calendar week archives in v1.26.0 of 11ty-subspace-builder. That gives the timeline a few more ways to browse older entries without flattening the chronological flow.

Published the first follow-up entry in the new threaded timeline model.

Timeline entries can now point back to earlier entries, which turns the feed into more of a build log than a flat list. This update continues from the original timeline launch and marks the point where parent and follow-up relationships became part of the feature.

The implementation for this lives in PR #17.

Added a personal timeline feed to the site. Markdown files in timeline/, same front matter as posts. Color is tag-driven: shipped goes green, published goes blue, thinking goes amber — no extra fields needed.
