v1.2: Dark mode that only changes the page

What's new

• Dark and sepia change only the page. The viewer's toolbar, sidebar and background now stay as they are. Before, dark mode inverted the whole viewer and turned the toolbar light grey.
• New icon, replacing the old grey one.
• Redesigned popup: position slider with a Reset button, and a short guide to the four buttons.
• Clearer buttons: the active mode is highlighted, the eye shows a slash when the toolbar is hidden, and sepia has a proper coffee cup icon.
• Your reading mode survives the toolbar toggle. Hiding or showing the toolbar reloads the page; dark or sepia now stays on in that tab.

Fixed

• The fullscreen button sat on top of Chrome's "Save to Drive" icon. The default position is now 170 px from the right. If you already set your own position, it is kept.
• The extension's buttons were almost invisible in dark mode.

Install

v1.1 - Dark Mode, Sepia & Stability Improvements

This update brings highly requested visual modes and improves overall stability.

🆕 New Features

• 🌙 Dark Mode: Added a High-Contrast Dark Mode (pitch black background) that smartly inverts text while keeping images normal.
• ☕ Sepia Mode: Added a warm, paper-like tint for reduced eye strain.

🛠️ Improvements

• Stability Fix: Removed keyboard shortcuts to prevent "focus trap" bugs where the browser would block keys when the toolbar was hidden.
• Visuals: Updated icons to a soft off-white color for better visibility on all backgrounds.

📦 Installation
