News & Research
Deep-reads of every substantive source that shaped the April 2026 Briefing. Each page summarises one article or community thread with a consistent format: headline → key takeaways → full notes → what to actually do → related Playbook pages. Cross-linked to the reference documentation so you can always jump from “what’s the news” to “how do I implement this.”
Use this section when you want to go deeper than the briefing but don’t have time to read every source yourself.
