- The `/system` FAT volume is removed. Its files are embedded in the firmware as generated C arrays.
- Default-size fonts are generated at build time and used from flash.
- The LVGL task and the Launcher run on PSRAM-preferred stacks. A new kernel `file_ops` API takes the file work off those threads.
- `MainDispatcher` is reimplemented as an on-demand task.
- More long-lived state is allocated with the PSRAM-preferring helpers.
