An editing pass over the words around the game, and three corrections in the guide

The guide, the hall, the room page and the explanations after a turn
lose their closing aphorisms, most of their semicolons, the
statement-colon-example lines and the page narrating itself. The
tagline is one sentence, and 'a labor of love' is gone from the about
link. The chronicle's imagery and the in-world names stay.

Corrected along the way: a counter-spell does stop wound spells and
lightning (the guide said it did not); a shield is not the only defence
against a newly summoned creature; on the first turn a knife can hurt
you; a palm is no defence against a fireball; a goblin needs five turns
to match one; and only the offline duel lives in the browser.
