/**
 * THE INNERMOST CONTROL CLAIMS THE PRESS (`docs/accessibility.md` § Focus & tab
 * order).
 *
 * A DOM `<button>` bubbles, so a control dropped inside a pressable surface runs
 * that surface's handler as well as its own: a ⋯ inside a register row opens the
 * record AND the menu, a `RowFocusEntry` runs its row's handler twice. The control
 * therefore stops the press at itself, and this is where that is written — one
 * rule with one implementation, rather than the same three lines re-typed at
 * every control that takes an `onPress`.
 *
 * A plain function, not a hook: the rule is about the EVENT, so it also holds
 * for a handler built per row inside a `map` — where a hook could not be called
 * at all, and where the three lines would otherwise come back.
 *
 * It answers `undefined` when there is nothing to press, so a row that goes
 * nowhere never swallows the press of the surface it rides — a non-control has
 * no claim to make.
