Proofs, honest
This room turns the mirror on the site itself. Not a metaphor, the actual measured numbers from the build that made the page you are reading right now, and a plain account of what the site talks to and what it costs.
What it is built with
What it talks to
How it is rendered
Every Estate page and every room prerenders to real static HTML, per route, per language, before a crawler or a slow connection ever runs a line of JavaScript. The interactive layer boots underneath afterward, unchanged, for a visitor whose browser can run it.
What each room weighs
Gzipped JavaScript, one room's own code-split chunk. A visitor pays the Estate shell once, then only the rooms they actually open, per the CONSTELLATION-SCAFFOLD code-split rule.
three.js/R3F, by far the heaviest room. Only paid by a visitor who actually opens /brain, never by anyone else.
Measured at the last build that touched a room, not fetched live.
What it costs
Right now, nothing, because it is not live yet. This is a staging repository (buge4/bjornvhauge-com), not a domain. When it does go live, the honest projection is $0 in ordinary running cost: static files on a CDN, no server process, no database, no paid API key anywhere in the stack above. If that changes, this room changes with it, not the other way around.
