 * Determines if a click landed in the empty space of a VariableInput and returns
 * the correct target position to place the caret, or null if no correction is needed.
 *
 * This handles two cases where the browser's native click handler misplaces the caret
 * inside a flex-layout ProseMirror editor with non-editable variable chip nodes:
 *
 * Case 1 (depth === 0): posAtCoords returned {inside: -1}, meaning the click didn't
 *   land inside any node. The resolved position is at the doc level.
 *
 * Case 2 (depth > 0, clickX past content): posAtCoords returned a paragraph-level
 *   position, but the click coordinates are past the visible content's right edge.
 *   Common when content ends with a variable chip.
