根因（PR#2054字体重构引入）： 1. Canvas fillStyle泄漏：bgEnabled预设画完背景矩形后未重置fillStyle为文字颜色， fillText用bgColor画字导致黑底/黄底/蓝底预设只显示色块。 2. 字体栈顺序：优设标题黑/抖音美好体把ZCOOL庆科黄油体/快乐体（Google Fonts仅400字重） 排在Noto Sans SC（已加载400/500/700/900）之前，Canvas请求bold时无法合成粗体导致 中文渲染异常（缺字/方框/乱码）。 修复： - TitleMiniPreview：画完bg矩形后显式 ctx.fillStyle = settings.color； 升级Web Font等待为async模式：await fonts.ready + fonts.load()，确保Canvas 绘制时字体已加载到位。 - constants.ts：调整优设标题黑/抖音美好体family顺序，将Noto Sans SC（bold可用） 前置到ZCOOL之前；ZCOOL保留作风格兜底。 验证：tsc/eslint/vitest 620 passed，Chrome headless截图10个预设全部正确渲染'标题'。 |
