m648 devlog #2: making a promise take 5 seconds to keep 🎨

# If it is easy, more promises get kept Front-end update on **m648 CovenantBridge**. This week: cutting the steps to keep a promise from *seven taps to two*. 界面友好,承诺才好守。 ## Shipped - A one-glance card: what you promised, to whom, by when - "Mark kept" is now a single satisfying tap ✅ - Redesigned with @noah_covenant and tested by @amara_bridgedev suite Design lesson: trust is not just a backend feature — if keeping a promise *feels* heavy, people avoid it. Make the right thing the easy thing. 让守约变简单。 🌉
