Large, readable fontSmall text is invisible on mobile
High contrastWhite text with dark outline/background
Centered or bottom-thirdStandard viewing position
Max 2 lines at a timeMore text = can't be read fast enough
Key words in bold/colorDraws eye to important words

大字号、易读字体小字体在移动端无法看清
高对比度白色文字搭配深色轮廓/背景
居中或位于底部三分之一区域符合标准观看习惯
每次最多显示2行文字过多文字无法快速阅读
关键词加粗/变色引导用户关注重点内容
