/**
 * Turns a viewport click point into a FeedbackPayload["anchor"] (schema v2):
 * position percentages, selector, element identity (tag/id/testid/role/
 * text/label/rect), and structural context (nearest heading + landmark path).
 *
 * CRITICAL: the crosshair capture layer sits on top of the page, so a naive
 * elementFromPoint would resolve to the widget itself. We (a) temporarily set
 * the capture layer to pointer-events:none and (b) walk `elementsFromPoint`
 * skipping every node inside the widget host. The resulting target is always
 * a HOST-page element, never one of ours. Nothing here throws — selector /
 * element / heading / landmark are null on any error.
 *
 * PRIVACY: input values are never captured. For input/textarea/select the
 * `text` field is always null (label may carry placeholder/aria-label).
