Build a Chrome extension called "Pomodoro Focus" that combines a Pomodoro timer with automatic site blocking. The extension should: (1) provide a popup with start/pause/reset Pomodoro controls, default 25min focus / 5min break, (2) during focus intervals, automatically block user-defined distracting sites (block list set in options), (3) during break intervals, sites are unblocked, (4) show a notification when an interval ends, (5) keep a daily count of completed Pomodoros visible in the popup, (6) allow customization of focus and break durations in options. Permissions: storage, declarativeNetRequest, alarms, notifications. Manifest V3 with service worker and declarativeNetRequest for blocking.

What this extension does

A Pomodoro timer that automatically blocks distracting sites during the 25-minute focus intervals and unblocks them during 5-minute breaks. Counts daily Pomodoros, sends notifications, fully customizable.

How it works

A service worker manages timer state via chrome.alarms. During focus intervals, declarativeNetRequest rules block listed domains. The popup polls timer state for live UI updates. Notifications fire on interval boundaries.

Permissions used: storage, declarativeNetRequest, alarms, notifications
