Spool Studio 3.1.2

This patch fixes dark text on the dark NFC/RFID settings background (issue #11).

• The NFC/RFID tag storage descriptions and Native tags only label now use explicit light text colors.
• Settings cards provide a matching light default content color, keeping unstyled text readable on their dark background.
• Tag-storage checkboxes, migration controls and tag-link buttons use the existing dark UI palette.
• Migration preview/result dialogs and the unlink confirmation now use matching dark backgrounds and light text.

The changes affect presentation only; tag lookup, migration and storage behavior are unchanged.

Validation: debug build and Android Lint completed successfully. The affected settings text and checkbox label were visually checked in the Android emulator.
