## Description

<strong>Zenith Reader</strong> transforms any article into a clean, focused reading experience — no clutter, no ads, no distractions.

Features

<strong>🧹 Clean View</strong>
Intelligent DOM purification scores and extracts the main article content, hiding navbars, sidebars, ads, and everything else automatically.

<strong>🎨 Four Themes</strong>
Switch instantly between Light, Dark, Sepia, and Nord themes. Font size, line height, and typeface are all adjustable.

<strong>👁 Bionic Reading</strong>
Bolds the first letters of every word to guide your eyes and increase reading speed — toggle on or off anytime.

<strong>🎯 Semantic Media Filter</strong>
A built-in heuristic engine distinguishes contextual images from decorative ads and tracking pixels, removing the noise automatically.

<strong>📝 Smart Annotations</strong>
Highlight any text and it's saved locally to your browser. Highlights persist across sessions — even if you restart Firefox.

<strong>⬇ Auto-Scroll Flow</strong>
Hold the spacebar for 600ms to engage smooth, variable-speed auto-scroll. Hands-free reading at your pace.

<strong>📊 Reading Progress</strong>
A live progress bar shows how far through the article you are, with a dynamic "X minutes remaining" estimate based on your scroll speed.

<strong>∑ Private AI Summary</strong>
Connect to a local LLM (Ollama, llama.cpp) running on your own machine. Get instant article summaries — <strong>no data ever leaves your device</strong>.

<strong>🛡 Hard Focus Mode</strong>
Locks you into your reading tab for a set duration. Tab switching is blocked so you can read without interruption.

<strong>💾 Offline Snapshot</strong>
Save any cleaned article as a self-contained HTML file for offline reading — no internet required.
