Bug Fixes & Improvements - Fixed an issue where activity logging (feed, sleep, diaper) could silently fail in certain conditions. All recording buttons now work reliably. - Improved error handling: if something goes wrong while saving an activity, you'll now see a clear error message instead of silent failure. - Activity data now refreshes immediately after logging, so your dashboard and timeline stay up to date. - General stability improvements and minor UI polish.
