/*
 * Moyako Games — Info Drawer
 * ------------------------------------------------------------------
 * Overlay drawer used on every game page (About / Rules / Tips / FAQ).
 * Independent of moyako-components.css so it loads on the 6 non-v2
 * games as well as chess. The drawer must be position:fixed + high
 * z-index so opening it doesn't push the board or render inline.
 *
 * Opened state = .is-open on .info-drawer.
 * PR-7b-era markup lives in each game's HTML; this file only styles.
