The page

Title. Gesture. Body. Plain terms. Optional source. Always one screen.

Every page in a sveltekitbook follows the same skeleton. The title is what this page is. The gesture is the one sentence the reader could quote back. The body is the argument — under 400 words. The "in plain terms" block is the same idea, simpler, for a reader without your background. Source and citation are optional. None of this is enforced by code; it is the discipline the format invites.
