??? · not in the nav on purpose
You found the vault.
There's nothing load-bearing here. No lore, no secret backend, no real inventory. Just a tiny 🚪 tucked into the sidebar of every page on this site, quiet until you go looking for it. You went looking. That's the whole point.
If a little toast popped in the corner just now, that's real, not a screenshot. It's stored in your browser only (nobody else's visit, nobody's server), so it'll still be there next time you're back on this device, and gone the moment you clear your storage. Which feels about right for a room nobody officially told you about.
