/* Hallmark · pre-emit critique: P4 H5 E4 S4 R5 V4
 * Hallmark · component: mines field · genre: atmospheric (the site's obsidian + gold) · theme: site tokens
 * states: tiles -- hidden (default), hover, :focus-visible, :active, aria-disabled, aria-busy
 *         (waiting on the server), gem (success), boom (error), and the end-of-game reveal;
 *         the one button -- start, cash out, busy, disabled; the stepper and picks share them.
 * signature: the field is Minecraft's own -- raised blocks that sink when turned, a diamond or
 *            the TNT inside -- and when a game ends every tile is shown, so the field the player
 *            was dealt is always on the screen, not only the tile that ended it.
 * motion: a diamond settling (260ms), the TNT going off (one shake). Reduced motion: none.
