/*
 * Hub-only appearance layer: shared account chrome + the hub dark mapping.
 * The hub loads this trimmed file instead of the full rg-theme.css (which
 * keeps the per-game dark palettes for the game pages).
 * Loaded after hub.css so the mappings below can adapt existing variables
 * without coupling theme behavior to page logic.
 *
 * 令牌层已收敛到 shared/css/rg-tokens.css(先于本文件加载):统一 --rg-* 令牌
 * 与共享账号 chrome 的 --rg-night-* 暗色板都在那里定义,本文件只引用。
