/**
 * Whether a press must be swallowed because the same gesture SELECTED text.
 *
 * A register row is a button wrapped around DATA. Dragging across a customer's
 * name ends in a click on the row, so without this guard the release navigates
 * to the record and discards the selection — the row's own press is what makes
 * its content uncopyable. Both of a row's press surfaces consult this:
 * `PressableRow` (the mouse) and `RowFocusEntry` (the blank space beneath the cells).
 *
 * Deliberately narrow. A plain click that got swallowed would leave the row
 * impossible to open, which is far worse than losing a selection, so only a
 * real, non-empty selection suppresses — and only a POINTER gesture consults it
 * on the door, which is the KEYBOARD target: a selection left anywhere on the
 * page survives a Tab, so a door that checked it on Enter would refuse to open
 * any row until the user cleared a selection they may not even see.
