/**
 * A bounded number, twice over: the exact figure in a stepper box, the whole
 * range under a slider beside it. It mirrors the control Creaditor's own editor
 * uses for a size (`cdtr-range-input` — a paper slider next to a number input),
 * so a font size set here is set the way an author already sets one there.
 *
 * The pair is drawn left-to-right in both languages: the box first, then the
 * track running from min to max away from it. A slider whose minimum sits on
 * the right reads as backwards even in an RTL panel, and the editor this
 * follows pins its own slider to `dir="ltr"` for the same reason.
 *
 * Unset stays a real state. The box shows the placeholder — the default the
 * renderer would use — and the slider rests where that default lands; typing or
 * dragging makes the value explicit, and emptying the box gives it back. The
 * slider itself never sits on nothing, so it can't be dragged from "no value"
 * without saying which value that was.
