* **New Features** * Time and delay utilities added (ticks, ms, µs); SD card now uses an expansion-header CS pin; HTTP downloads warn when run on the GUI task and yield to avoid blocking. * **Bug Fixes / Reliability** * Many hard-crash paths converted to guarded checks to reduce abrupt termination and improve stability. * **Tests** * Unit tests added to validate time and delay accuracy. * **Chores** * License header and build/macro updates.
