# 平台唯一配置表：只改这里即可。键 = 入库的 platform；label = 帮助/提示里的展示名；
# prefix = 默认账号名「{prefix}{序号}号」，省略时等于 label；
# aliases = 额外 CLI 称呼（英文键与 label 已自动参与解析，不必重复写）。
# 登录检测：仅看页面 DOM。匹配 anchor 的标签页上出现「未登录」选择器则未登录；否则视为已登录。
# - _LOGIN_LOGGED_OUT_DOM_GENERIC_SELECTORS：通用「登录」按钮/链接等（可被 login_skip_generic_logged_out_dom 关闭）。
# - login_logged_out_selectors：按平台追加；误判时也可用 login_skip_generic_logged_out_dom + 仅平台自选。
