The planet/ship-group sheets stay mounted on desktop but are hidden by a
media query (`display: none`); the document-level tap-outside listener
fired regardless, so the first click after selecting a planet cleared the
selection — breaking every desktop inspector/select flow in CI. Guard the
handler on the sheet's computed display (`offsetParent` is unreliable for
`position: fixed`). The swipe handle is naturally inert when hidden.
