/* Mines Duel: the lobby, and the arena where two players turn tiles on the same hidden field.
 * component: duel lobby + arena · genre: atmospheric (the site's obsidian + gold) · theme: site tokens
 * states: tiles -- hidden, hover, :focus-visible, disabled, aria-busy, gem, boom, and the end-of-game
 *         reveal (tnt, dim-gem); the lock button -- default, hover, disabled, hidden once locked;
 *         a side -- active (your move), waiting; the clock -- calm, urgent; the result strip -- won,
 *         lost, draw; a lobby row -- default, hover, mine; the choice chips -- default, pressed.
 * signature: the two boards are the same field. Yours is a full-size board you press; theirs is a
 *            small dark board that stays dark -- you can see THAT they are playing, never HOW --
 *            until the clock and the verdict bring every tile up at once.
 * motion: a diamond popping, TNT going off (one shake), the tiles of the reveal falling into place,
 *         the clock ring draining. Reduced motion: none of it, the result simply appears.
 * The tiles themselves are mines.css's .mtile; this file only supplies the variables they read.
