Showcase

There is not and will not be a single item here that affects the numbers. Not «not yet» — it cannot exist: the item has no field capable of granting a bonus, and a test checks that. §13 forbids selling advantage and §1 promises fair play; a shop where time or money buys power cancels both at once.

Leaning

Changes how you play, not how fast you grow: it does not touch the economy at all.

A leaning does not affect mining or research cost. That is deliberate: measurement showed any economic multiplier breaks §4.7 — mining feeds points and compounds, so even ±6% gave a 29% spread against a 15% limit.

The only place where players set the price, not the balance. Hence cosmetics only: an auction trading power is pay-to-win with extra steps.

A bid in the final minutes extends the lot — otherwise the winner is the one with the better ping, not the one who values it more.
