/* Shared layout scaffold for normal-flow game pages.
 *
 * Every game written before this file carries its own copy of the same
 * html/body, .game-container, .content, .title and .home-link rules, forty
 * near-identical blocks that a new game had to remember to reproduce. Games
 * that link this file get the scaffold for free and only write the styles
 * specific to their board.
 *
 * Opt-in on purpose. It is linked between main.css and the game's own
 * style.css, so a game can still override anything here, and the existing
 * fullscreen games (which set `position: fixed` on .game-container and are
 * detected by main.js) are completely unaffected because they never link it.
 *
 * Selectors stay at single-class specificity for the same reason: a game's
 * own style.css loads afterwards and must win ties.
