The plain statement leads through position, not through brightness. Label and hint stay in the same quiet tone. The activity signals are loud, and so is the elapsed time, which turns yellow after 6 seconds and red after 12, in the colour language of the save dot in the header. Below it an indeterminate bar runs at working pace (1.6s, linear): a determinacy sign that claims no percentage nobody has. The indicator appears from the first millisecond and fades out over 180ms at the end, so it never invents waiting time. Only after 6 seconds do the elapsed counter and the sawing Struqo craftsman join in, where distraction helps rather than slows. Under prefers-reduced-motion the stripe holds still, the text remains.

Page title with slots for title, actions, breadcrumb and a meta line, with an optional divider. It sits inside the page and is not the app-shell chrome (that arrives as its own organism).

Label, helper text, error message and the a11y wiring around any control. The error state sets aria-invalid and tints the border. Control-agnostic: input, select or textarea.

The centre of the editor bar carries place, mode, switching and creation. Three levels: project, sheet, mode. The mode segment appears only on 3D-capable sheets; a perspective shows quiet 3D, a plan shows nothing.

One selection list for five instances: project, sheet, type, snap step, unit. The entry in force is marked and stays selectable; disabled is reserved for what does not exist. Click the button to open, Esc closes it and returns focus.

List-item container in three variants: static for passive info, interactive with a hover state, and with an actions menu for secondary operations. The card body is always the primary click target. Secondary actions live in the ⋯ menu in the top-right, never as parallel buttons.

The drawings rail shows per view whether the projection still matches its source plan. This is not a save status: it knows nothing about the network or the server, it only compares derivation against source. A closed ring means complete, an open arc means something is missing. One click brings it up to date.

A sheet of the example as a way into the editor. With a head line it sits as on a board, the image 8 px below its baseline. Without it, it appears like this on the subpages.

Dimming: what carries the message stays bright, the result on the drawing area and the marked control. Everything else is darkened when the image is taken, 50 % in the light and 60 % in the dark image.

Key facts in the tone of a plan. Each field takes two modules of the register, the lines move no baseline.
