- Added `read_lines` function to `detector.py` for OCR of multiple text lines in a specified region, improving the ability to dynamically locate text in the UI.
- Rewrote the gem shop task in `gem_shop.py` to utilize OCR for sidebar navigation and free card status checks, replacing fixed coordinates with dynamic text detection.
- Introduced helper functions `_find_sidebar_label`, `_on_general_products_tab`, `_ensure_general_products_tab`, `_read_card_lines`, `_read_free_card_status`, and `_find_buy_button` to streamline the OCR process and improve reliability against UI changes.
- Removed outdated color probe methods for checking the free card status, enhancing the robustness of the gem shop interaction flow.
- Live-calibrated the new OCR functionality to ensure accurate detection of UI elements and their states.
- Recalibrated gem shop task after client UI update, replacing the old overlay dialog with a full subscreen.
- Removed custom dialog open/close checks in favor of shared navigation functions.
- Updated method names and logic to reflect new tab structure and improve clarity.
- Enhanced error handling for dialog closure and navigation return to home.
- Verified live against real account states to ensure functionality and correctness.
- Added `ba_auto/tasks/gem_shop.py` to automate claiming the daily free package from the gem shop.
- Integrated color probes for state detection instead of template matching.
- Updated `ba_daily.py` to include the new gem shop task in the default execution order.
- Documented the implementation and calibration process in `plan.md`, including live testing results and fixes for dialog handling.
- Addressed potential bugs related to dialog state verification and tab layout changes.
