- JSON layouts (en-US, sv-SE inheriting number/symbol layers via base) - LayoutModel + KeyGeometry: proportional rows, nearest-key hit testing - KeyboardSurface: multi-pointer touch/mouse routing to the controller - KeyboardController + ShiftState: iOS shift/caps-lock, layers, globe, dismiss - QML view with light/dark iPad palette and drag handle - DevHooks: SLOPOSK_AUTOTYPE, SLOPOSK_SCREENSHOT for headless checks - Unit tests for shift, loader, geometry and controller Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
