Use at your own discretion. Running userscripts always carries some risk, including the possibility of account restrictions or bans depending on site policies. This script is safe from a malware perspective, but you should still be cautious when installing any third-party extensions or apps outside your main browser.

Description
This userscript automatically farms stamina for the game Veyra on demonicscans.org by clicking on reaction buttons across manga/manhwa chapters.
Once enabled, open any chapter from any series (ideally a long-running one like One Piece) and the script will:
- Scroll to the reaction button and click it.
- Automatically move to the next chapter and repeat the process.
- Show a small on-screen HUD with your current stamina and farm progress.
- Pause if you are within 30 stamina of your maximum.
- Stop completely when the daily farm limit (e.g.
1000/1000) is reached. - Allow manual pause/resume with a toggle button in the HUD.
- Automatically detect if you are logged out, log in using the provided credentials, and resume farming from the last chapter.
