Architect layer
Design
The name, addresses, meta and appearance of this project. Saved settings are read at runtime — a change shows on the next page load, with no rebuild.
Dialogs
The one modal window this project has, shown in its real settings. Press a button — the real window opens, not a picture of one.
Plain
A heading, an explanation, a cross. A reference window is closed, not confirmed — so it has no buttons at all.
With buttons
A footer that stays put. Buttons belong to the WINDOW, not to the body — otherwise they scroll away with the text.
Long — this is the one that matters
The body outgrows the screen and scrolls; the heading and the buttons stay. Exactly what a hand-built window loses.
Cannot be dismissed
No cross, no Escape, no click-outside. One lawful use: refusing access.
