01 — The companyLjubljana
RACUNAJ NAME d.o.o. works from Vodnikova cesta 31 in Ljubljana. The work is the ordinary, unglamorous kind: ledgers that balance, returns filed on the day they are due, and somebody who picks up when a question cannot wait.
A page is a poor instrument for that sort of work, because none of it is bought from a website. What a page can hold is the registry entry, an address that reaches a person, and enough of a demonstration that the arithmetic here is taken seriously. Those are the four lines below.

Bookkeeping, deadlines and anything to do with the firm: pisarna@racunaj.online. The app, or this website: zaboj@racunaj.online. Post arrives at Vodnikova cesta 31.
Both are opened by a person rather than sorted by a system, so a couple of plain sentences about the matter at hand will travel further here than any contact form.

04 — One measurable thingcounted
Anything you can shove but not pull obeys this, whether it is a crate, a wardrobe or a pallet. Push it flat against a wall and it will only ever travel along that wall. Push it into a corner and it will not travel at all. Count the squares where each of those is true and the floor turns out to be far less usable than it looks.
Tap a register, then the keys. The room is the clear floor inside the walls, measured in squares along one side.
Room 3 to 40 · things 1 to 40
In a six-by-six room, 20 of the 36 squares — 55.6 per cent — restrict a pushed object to a single line or freeze it outright, and four of those are corners it can never leave. Scatter five things across that floor at random and the chance every one of them stays fully movable is 1 in 58.
Worked out by the rule itself rather than by a formula: a thing at a square can be pushed in a direction only when the square behind it and the square ahead are both clear floor, so each square is tested against all four directions and sorted by how many survive. That sorting was run over every square of rooms from three to forty a side, and it agreed exactly with the closed count — (m−2)² squares with four directions, 4(m−2) with two, and four corners with none. The chance of k things all landing on fully movable squares is ((m−2)²/m²)^k, which a four-hundred-thousand-drop simulation matched to within three hundredths of a percentage point. Absent by design: this is a bare rectangle with nothing inside it — no inner walls, no marked destinations, no objects, no puzzle and nothing that can be shoved anywhere. The arithmetic describes a floor and stops there. Working a loaded storeroom out move by move is a different occupation, and it is not conducted on this website.
05 — On Google Play1 listing
The firm also publishes one app, and the arithmetic above is the whole reason it exists. Zaboji is a storeroom puzzle: crates that can be pushed and never pulled, and a floor with far fewer safe squares on it than first appears. No connection is opened, no account is kept and nothing inside it is sold.
