/**
 * Reports whether a CSS line-clamped element is actually overflowing — i.e.
 * its content is taller than the clamped box (`scrollHeight > clientHeight`).
 *
 * Used to drive "show the affordance only when the text is really cut":
 * a tooltip on a clamped title, a "Read more" toggle on a clamped body.
 * Because line-clamp keeps the full text in the DOM, this is purely a
 * sighted-user convenience — assistive tech reads the full text regardless.
 *
 * Re-measures on element resize (a narrower column wraps more, so a title
 * that fit at full width may clip in a two-column grid). `enabled` lets the
 * caller switch measurement off — e.g. while a description is expanded, there
 * is nothing to measure.
