Rajshekhar142/antiDiary_failSafe — reverse-engineered prompt

Build me a very simple fail safe landing page for antiDiary that can stay online even while the real app is still being finished. I want it to feel calm, trustworthy, and intentional, not like a broken site. The page should clearly tell visitors that antiDiary is temporarily running in a limited mode, reassure them that the full app is on the way, and give them a clean place to land instead of an error screen.

Please make it work nicely on both phones and laptops, load fast, and stay lightweight. A single HTML page is fine, with basic styling and only a little JavaScript if it actually helps. Include a clear heading, a short human sounding explanation, and a simple message that encourages people to come back soon. If it fits naturally, add a small contact or status note too.

I want something polished enough that I could put online right away as a dependable backup page while the main product gets production ready.
