## What The Pillar is
The Pillar is a browser game and advertising marketplace. A window is a licensed ad pane on a 3D tower, not real property and not a security. One tower stands on the screen. Each pane of glass can be lit by a company: its name, logo, and link glow on the pillar for as long as the licence runs. The tower has 1920 panes across 80 floors (four faces, six panes per face).

## How leasing a window works
Sign in with X (Twitter), pick a pane, and paste a company URL. The Pillar fills the window with that brand automatically. Occupancy is an advertising licence for a set period — not ownership of anything, not real estate, and not a security. Paid occupancy is a monthly licence charged through Stripe and renews until cancelled; during preview some windows may be free.
