Three more cautions: the un-grabbed chest, the biting ground, the starved draw

Ending a turn on a treasure nobody picked up now asks first (unless the
auto-grab preference is about to take it, or the grab would be refused —
laden arms, weakness, spent actions, glue, a locked safe, or your own
home where the chest already scores; the view learns gluedCells and
openSafes so the check is honest). Stepping onto ground that bites —
thornbush, tacks, pit, ooze — warns with the exact price, unless you are
mist. And the sticky draw picker no longer quietly starves anyone: a
draw below what would fit asks too.
