nonValidSlideId
function nonValidSlideId(value: unknown): boolean;
nonValidSlideId(value) is the same test as !isValidSlideId(value), written so that a guard clause reads as a sentence rather than as a negation.
Letters, digits, hyphens and underscores, at least one of them. Slide ids are short — p1 is a perfectly ordinary one — so no minimum length is imposed.
isX and nonX answer a question and never interrupt control flow; requireX and requireNonX hand the value back or throw. The scheme is explained in Validation conventions.
