/* Neft Calm & Accessible Games layer (additive, gameplay-neutral).
 * Injected by tools/inject-game-access.js. Pairs with assets/game-access.js.

 * Scope: accessibility + calm-mode polish ONLY. No gameplay logic, no colors
 * that override a game's identity beyond focus/controls. Everything degrades
 * gracefully — if the JS fails to load, these rules are inert.
