Send word: a way to reach the keeper

The about panel gets wizwar's contact paragraph (mail, Bluesky, Mastodon,
the source), and the colophons, the guide and the rules page each carry
a one-line way to report a rule read wrong.

 		<h2>A first duel</h2>
 		<p>Open with a wave on each hand. From W-W you may turn either hand into a counter-spell (W-W-S), a protection from evil (W-W-P) or resist heat (W-W-F-P), and nobody can hurt you on the first turn. Watch the warnings: when a missile is one gesture away, a palm costs you one hand for one turn; when a fireball is one gesture away, only a counter-spell, a resistance, or a counter of your own will do.</p>
 		<p>Then choose a spell from the sheet and pin it to a hand, and keep the other hand for answering. Cause light wounds is three gestures, a fireball five, and summoning a goblin three; a goblin that lives for four turns has done a fireball's work. Read the rival's ledger every turn as they read yours. Both of you are bluffing, and the whole page is the paper.</p>
