Replace the Unix simulator ctypes dependency with uctypes.addressof, since the CI Unix MicroPython build does not enable FFI/ctypes. Use a bytearray for the preallocated buffer so rangeproof code receives writable memory.
Wrap lv.buttonmatrix with legacy helpers used by input and mnemonic screens. Update the affected screens to use LVGL 9 textarea, switch, style, and event APIs.
Replace remaining deprecated LVGL widget, style, event, and alignment APIs in GUI/app screens. Update QR controls, modal prompts, settings switches, wallet and transaction views to use native LVGL 9 patterns.
Restore the PIN setup screen closer to the pre-upgrade reference by resetting screen/button styles, hiding keypad hit areas, tuning text sizing, and removing the empty battery artifact.
Scale shared button labels through a common style and recenter them using their transformed pivot so reduced text stays visually centered.
Restore mnemonic table styling and word switching behavior after the LVGL 9 port. Reuse shared muted hint colors and buttonmatrix styles for the edit panel.
Restore wallet QR card sizing, alignment, and fullscreen redraw behavior after the LVGL 9 port. Disable scroll artifacts and keep QR alert pages transparent.
Apply shared transparent page styling and disable default scrollbars so prompt and transaction detail screens match the legacy layout.
Restore transparent textarea styling, left-aligned wallet names, and focused cursor behavior so the edit screen matches the legacy reference.
Apply shared transparent textarea styling to derivation and numeric entry screens so editable fields avoid LVGL 9 theme background and font drift.
Use fixed-size QR rendering and tighter insets so wallet and xpub QR screens keep stable dimensions across redraws.
Keep topbar and menu button style_t objects reachable after assignment to LVGL objects. Disable QR payload prints by default and clear cancelled QR animation task references on DELETE.
Keep button clicks working while restoring touch entropy collection during presses. Clean up label alignment, modal/QR control styling, settings switch labels, and long transaction detail scrolling.
Describe legacy widget compatibility methods and keep sensitive simulator QR payload logging opt-in for explicit diagnostics.
Keep dynamic QR styles reachable, guard screen cleanup, and prevent stale keyboard hints.
Replace manual arc rotation with the native spinner so QR scan and smartcard wait screens render a full ring without the knob artifact.

Summary
This PR upgrades
specter-diyto MicroPython v1.25 and LVGL v9.3, including migration of the application code to the updated MicroPython and LVGL APIs.The application migration is technically complete, and the firmware runs in the simulator. This PR remains a draft while the remaining hardware-specific issues are being resolved and the firmware is validated on the target device.
Unlike an early WIP PR #304 , this draft is now closer to merging: the main remaining goal is to confirm that the updated code works correctly on real hardware, test it thoroughly, and avoid regressions.
IMPORTANT
This draft PR currently has temporary submodule pointers to developer forks. These must be replaced with organization-owned repositories before merging.
