A Chromium extension that dynamically detects baked-in black bars (letterboxing) in YouTube videos and zooms to fill your screen with actual content — without cropping real video.

## The Problem

Many YouTubers bake cinematic black bars into their 16:9 video (e.g., 21:9 content inside a 16:9 frame). On an ultrawide monitor, this means black bars on **all four sides** — pillarboxes from the 16:9 viewport, plus letterboxes baked into the video itself. You lose significant screen real estate.

Existing "zoom to fill" solutions (like Plex HTPC) aren't intelligent — they blindly zoom all content, cropping real video when no bars are present.

## How It Works

AutoZoomer samples video frames to a small canvas (16x128 pixels by default), scans for black bar boundaries using multi-column consensus, and applies a CSS transform to zoom the video — pushing the bars off-screen while keeping all real content visible.
