24h Auto Button Click Script

I’m looking for a simple JavaScript snippet that automatically clicks two specific buttons on a static HTML page once every 24 hours.

Key points
• The page is strictly static—no frameworks or authentication layers involved.
• The buttons can be uniquely targeted by their class name.
• No pop-ups, alerts, or additional interactions need to be handled.

Deliverable
• A lightweight, well-commented script (pure JS) that:
– Locates the two buttons by class name.
– Triggers a click on each of them exactly once every 24-hour cycle.
– Includes a concise note on how to embed or reference the script in the page.

That’s all I need—just a clean, minimal solution that does the job reliably.
