What it is
A single public board. Every row is a product website or an X @handle, and the rows are sorted by amount paid, highest first. Anyone can read it without an account. Anyone can join it by paying at least $1, and anyone already on it can climb by paying more.
This is new. There is no history here yet, no archive of past leaders and no numbers worth bragging about — the board starts empty and fills in the order that people pay. You can watch that happen on the board itself, which is the only page that really matters.
The one rule
Rank is the bid. Position is never stored on a listing; it is derived from the amounts every time the board is drawn, which means what you see is always the current truth about what has been paid. Equal amounts keep the order they were placed in, so the older bid holds the higher rank and matching someone parks you behind them rather than ahead.
That is the complete ranking logic. The rules page spells out the floor, the ceiling, the increments and what is allowed on the board, but none of it adds a second mechanism. There isn’t one.
