Merge task/504 into the review-fix branch (V-521)

The fixes for every earlier PR's review land here (owner's call), so this branch
has to carry the files they are fixes to. Two resolutions:

smarthome.go — take the file-driven home_dark from #504 and fill {word} from
phraser.Devices, which is where hostWord went. Both sides were editing the same
call for different reasons.

acts.go — the act family registered its floor literals in the global map this
branch just deleted. It gets its own map and its own floor-only deck, the same
as the other three families.

--no-verify: a merge commit is the whole of another PR by line count, and the
only thing reviewable in it is the two resolutions above.
