About This Project
This Pomodoro Timer is a beginner JavaScript project that teaches time management
app development using core web APIs.
The app implements the classic Pomodoro technique: 25-minute focused work sessions
followed by 5-minute breaks, with a 15-minute long break after every 4 sessions.
Features include a circular SVG progress ring that fills as the timer counts down,
browser notifications when sessions complete, audio alerts with mute toggle,
a settings panel with focus trap for accessibility, keyboard shortcuts (Space to
start/pause, Escape to close settings), and localStorage persistence for user settings.
