What it draws

The sheet the command line renders: hours across, a row per screen, every session as three strips — preshow on the ink hatch, the feature in cream (white in prime), the turnaround on the orange hatch. On a phone, the booth strips. A week or a festival draws day by day. It prints as the sheet prints.

What it does not

It does not solve and it does not check. The proof is the checker's and the checker is not here, so the board prints what the grid claims and says so. A grid without its brief is drawn by id. The files are read by this page and go nowhere.
