Fix the Flex geliştiren: Fix The Flex

Fix the Flex adds a live GPA calculator directly onto the FAST-NUCES FlexStudent portal's marks page.

Features:
- Floating widget showing each course's obtained/total marks, percentage, letter grade, and GPA, updated live as marks are uploaded
- Semester GPA (SGPA) banner, weighted by credit hours
- Auto-fills the portal's "Grand Total" table when the university leaves it blank
- Inline course badges and a toolbar popup summary
- Attendance tracker showing remaining allowed absences per course

All calculations use FAST-NUCES's official grading scale and run entirely in your browser — no data ever leaves your device. Projections only; not an official transcript.
