-- 平台检测与配置 (必须在 includes 之前)
-- ==============================================

-- 检测目标平台 - 优先级：命令行 > 环境变量 > 默认值
local target_platform = "switch"  -- 默认 Switch 平台

-- 方式1: 检查命令行传入的平台配置 (最高优先级)

    end
-- 方式2: 通过环境变量检测 PC 平台
elseif os.getenv("E2D_PLATFORM") == "pc" then
    target_platform = "pc"
-- 方式3: 检查 platform 配置
elseif has_config("platform") then
