Detailed Description

Typed wrappers that carry rendering-control intent for a form field.

morph::forms::Multiline and morph::forms::Ranged<Min, Max, Step> are thin field-type wrappers in the same family as morph::forms::Choice (choice.hpp): each carries a rendering control preference in the C++ type itself — Multiline says "edit me as a text area", Ranged says "edit me as a slider with these bounds" — and morph::forms::schemaJson surfaces that preference as the x-widget (and, for Ranged, x-min / x-max / x-step) schema annotation(s). See docs/spec/forms/widget_hints.md for the full design.

Neither wrapper changes what travels on the wire: the glz::meta specialisations below reflect each type's bare payload directly, exactly as Choice does, so Multiline serialises as a plain JSON string and Ranged as a nullable number.
