Prototype
Personal Project
Weekend hack to see if mdBook preprocessors could render interactive timelines. Hand-crafted HTML injected via a simple regex replace.
What Makes This Different
This page uses timeline-marker = "journey" in book.toml:
[preprocessor.timeline]
timeline-marker = "journey"
The marker word is fully configurable — use {{era}} for historical timelines,
{{sprint}} for agile retrospectives, or any word that fits your domain.
