* **New Features** * Added NFC chip-select to SD card hardware configuration. * **Refactor** * Consolidated and renamed icon resources; apps and status-bar now reference unified icon headers and new icon constants. * Renamed LVGL lock API (timed → lvgl_try_lock) and updated callers. * **Documentation** * Updated module README and license files; added Apache-2.0 license document.
