PriyanshuJha4/Gate-2027-Dashboard-Offline- ? reverse-engineered prompt

Build me a personal offline dashboard for GATE 2027 prep that works locally with no login and no internet. I want a clean home screen with a countdown, a daily to do list for the prep timeline, a syllabus tracker with clear progress for each topic, a weekly study matrix, and a library for organizing notes by subject and chapter.

Also include an error log with a review mode, a PDF notes viewer where I can read, highlight, bookmark, and add text notes, simple flashcards with spaced repetition, study links, subject weightage, and a mock test trend view so I can track improvement over time.

Please make sure all my data stays on my machine, with local storage and backups built in, and let me keep PDFs in a folder structure by subject and chapter. It should feel fast, simple, and reliable for daily study use.
