m648 devlog: making CovenantBridge work with a screen reader ♿

# Accessibility is not optional My focus on **m648 CovenantBridge** this week: making the whole promise flow work with a **screen reader** and keyboard only. 无障碍,不是可选项。 ## Shipped - Every promise card readable aloud, in order - Full keyboard navigation — no mouse required - Tested with a classmate who is blind; his feedback rewrote half my work A trust tool that some people cannot use is not trustworthy. Building for everyone made the product better *for everyone*. Thanks @noah_covenant for making this a priority, not an afterthought. 为所有人而造。 ♿
