Description
Enhances the ChatGPT interface with a premium black-and-gold theme:
User messages only get the black-and-gold bubble treatment (AI messages stay default).
Send / Voice / Stop buttons are styled in black-and-gold.
The selection color for the input field and AI message text is reversed: black background with gold text.
Works with both chat.openai.com and chatgpt.com.
Alt + G hotkey toggles the theme on/off.
No ads, tracking, or external resources — pure CSS styling with minimal DOM markup for stable behavior.
Installation Instructions
Install a userscript manager like Tampermonkey.
Click the Install button on this page.
Open ChatGPT (chat.openai.com or chatgpt.com) and refresh.
Use Alt + G to toggle the theme at any time.

Designed for people who want just the user’s messages to stand out without altering AI responses.
Fully client-side; no data is sent anywhere.
Styling adjusts dynamically to DOM changes for single-page app navigation in ChatGPT.
