## Notes:
- Requires Notcurses development headers/libs.
- Behavior may vary across terminals; see the implementation for details.
- When Fun is built without Notcurses (FUN_WITH_NOTCURSES=OFF), these opcodes still exist but perform no-ops and return -1/0 as documented, allowing scripts to degrade gracefully.
