/**
 * Codegen-side decomposition of the Collapsible Text primitive.
 *
 * The GUI's `collapsibleTextNodeToUIDL` mapper is *supposed* to bake the
 * clamp + overflow markers into the exported UIDL, but a project can be exported
 * without that decomposition (the primitive then arrives as the raw
 * `collapsible-text` element carrying only its content paragraph and the two
 * toggle labels). Doing the decomposition here as well means the generated app
 * clamps + gates the "Show more" toggle no matter how the UIDL was produced —
 * and stays idempotent when the UIDL *is* already decomposed.
 *
 * `state → style` is not expressible in the generated code, so instead of
 * toggling a line-clamp the body is emitted as TWO mutually-exclusive views of
 * the same content: a *collapsed* view carrying a static `-webkit-line-clamp`
 * (rendered when `expanded === false`) and an *expanded* view without it. Only
 * one mounts at runtime. The collapsed view is tagged `data-tq-collapsible-clamp`
 * and the Show more label `data-tq-collapsible-more` so the shipped
 * `TqCollapsibleTextOverflow` helper can measure real overflow and hide the
 * toggle when the text already fits.
