• 🖤 True #000000 Pitch Black Theme: Replaces default light/dark themes with pure zero-hex black for maximum energy savings on OLED & AMOLED screens.
• 🎨 Consolidated Styling: Restyles headers, footers, buttons, quote links, thread cards, reply boxes, and scrollbars for a clean, unified aesthetic.
• ⚡ Zero Latency (document-start): Runs at the earliest possible stage to eliminate flash-of-unstyled-content (FOUC).
