Landing: Minds' project paragraphs, estates as what we are building, Aetheria reconciled

Adds a "What the Minds are working on" section (Nibu, Aqua, Weksa, Libby,
Kiko, Heimdall), rewrites the estates intro, and reconciles the Aetheria
row with "Why Aetheria Went Quiet" (quiet after 2021, until 2026).

 ## Four estates
 
-GameCult is building toward a multi-stakeholder cooperative, and its stakeholders fall into four classes, which we call estates:
+Estates are what we are building: a multi-stakeholder cooperative whose stakeholders fall into four classes.

 - **Members**: the people who build the work.
 - **Clients**: those who commission work or depend on what we ship.
 - **Patrons**: the people who support the work.

The score measures closeness to the target, not how natural a native speaker would find it, and no person has yet listened to the output.</p>

 ## Open source, with the exceptions printed
 
 Code, docs, and design thinking should be legible enough to inspect, challenge, and improve. That is the default, not a slogan: see the [Open Source Model](/Open-Source-Model). Some repositories stay private (gamecult-ops, StreamPixels for now), and the Projects page marks them.
