Multi-tenant billing API
Tenant isolation, an audit trail per event, and reconciliation down to the cent.
Billing is the subsystem where a rounding error becomes a phone call. An audit trail is not a non-functional requirement here: it is the product.
In the final build the article body comes from PostgreSQL as semantic HTML, server-rendered so crawlers read the full text without depending on the 3D layer.
The article view drops the constellation effects and prioritises reading: 60 to 72 character measure, 1.78 line height, contrast above 4.5:1. The origin star stays noted in the footer so the reader keeps their place on the timeline.
On close, the camera returns to the exact point it left from, with no constellation reload.
