Apply a customizable night-mode color overlay to all websites in the current browser window

Reduces eye strain and blue light exposure during browsing, especially in low-light environments or during extended screen time

User clicks extension icon → popup opens with toggle, color palette, and opacity slider → user enables night mode and customizes settings → content script injects a full-screen div with the selected color and opacity using mix-blend-mode: multiply → settings are saved to chrome.storage.local and applied to all current and future tabs automatically

Target users: Users who browse at night or in dark environments / People sensitive to blue light or screen glare / Users seeking eye comfort during extended browsing sessions

The Chrome Web Store description is truncated ('Upgrad...') which may hint at a Pro version or upgrade prompt not visible in the source. However, exhaustive grep for 'upgrade', 'premium', 'pro', 'paid', 'subscription', 'billing' across all 64 source files returned zero matches, strongly indicating no paid features exist in this version.
Cannot verify if the extension vendor's website (https://chrome-tool.github.io/) offers a separate paid version or account system, as the extension source itself is fully self-contained and offline.

Monetization

No paid features detected

No paid features, billing, subscription, or upgrade gating found in the source code. The deterministic heuristic flagged 'upgrade' but grep across all 64 source files found zero matches for 'upgrade'. The Web Store description's truncated 'Upgrad...' likely refers to upgrading the extension itself, not a paid tier. The 'pro' keyword match in popup.js is just the CSS method setProperty(). All features (toggle, color selection, opacity adjustment, presets) are fully available without payment.

Reason: The extension is a fully local night-mode overlay tool. It uses chrome.storage.local for settings persistence and chrome.tabs/chrome.scripting for applying CSS overlays to web pages. There is no login UI, no authentication code, no external account creation, and no redirect to a web app requiring login. The core workflow (toggle night mode, customize color/opacity) works entirely offline within the browser.
