Live football commentary feeds on platforms like FotMob and Sofascore are continuously lazy-loaded, dynamically rendered, and frequently change their DOM class signatures. Hardcoded, site-specific CSS selectors break easily and fail to capture full match timelines.

Simultaneously, extracting clean prose from articles, blogs, Google Docs, and web PDFs is heavily obstructed by aggressive ad banners, paywall overlays, navigation clutter, and custom pagination. The challenge was building an adaptive dual-mode extraction engine that operates strictly client-side under Chromium's activeTab privacy sandbox without full-host permissions.

1. Density-Cluster Commentary Heuristic: Bypasses fragile CSS selectors by analyzing sentence density clusters across the DOM, identifying the commentary list, and executing programmatic auto-scrolling to accumulate lazy-loaded timelines.

2. Mozilla Readability.js Core: Embeds the proven Mozilla Readability engine (behind Firefox Reader View) to strip ads, sidebars, cookie banners, and navigational clutter, extracting pristine prose from news articles, stories, Google Docs, and PDF.js viewers.

3. Match Minute Precision: Intelligently parses timestamps (e.g., 45', 90+3') and halftime bullet notes across varied typography and apostrophe encodings.

4. Persistent Session Preview Panel: Instant preview with real-time character and word counts; captures survive popup closures and persist across the active browser session.

5. One-Click Copy & .txt File Export: Formats plain-text outputs ready for instant clipboard copying or .txt downloading.

6. Zero-Telemetry activeTab Security: Operates under Chromium's strict activeTab sandbox—only interacts with a page upon explicit user invocation with zero remote servers or telemetry.
