Claude OLED Dark real black από Dodo

Claude's built-in dark theme uses a soft #1F1F1E grayish background. On OLED screens that's wasted contrast and wasted battery.
This extension replaces it with a true #000000 canvas — sidebar, chat area, and artifact preview panel all flip to pure OLED black. The chat composer keeps a faint elevation so it still pops, and borders are bumped up so cards, dividers, and the artifact resize handle remain clearly visible. Hover states flash to white so interactive elements are obvious against the deep black.
Features
• Pure #000000 background on the chat, sidebar, and artifact preview panel
• Subtle elevation on the chat input (ChatGPT-style)
• Pure black tool-use cards, artifact cards, and code blocks
• Crisp visible borders on all surfaces against OLED black
• Hover states flip to white for clear interactive feedback
• Works on claude.ai, claude.com, and all subdomains
• Zero data collection, zero network requests, zero tracking
How it works
The extension injects a CSS file at document_start that overrides Claude's HSL background tokens and adds targeted rules for popovers, the composer, code blocks, and the artifact panel. A tiny content script keeps the page in dark mode if the site tries to flip it back to light.
