cirosantilli/expired-domain-names-by-day-2013 — reverse-engineered prompt

Build me a simple way to browse this expired domain name archive for 2013. I want to be able to open it in a browser, pick a month and day, and see the domain names for that date without digging through folders manually.

Please inspect the existing 01 through 12 folders and use whatever data format is already there. Add a search box so I can type a domain or keyword and see matching results across the whole year, with the date shown next to each match. It should also show basic counts, like how many domains are listed for the selected day and maybe the total for a month if that is easy from the files.

Keep it lightweight and easy to run locally. Include a short note on the page linking to the methodology URL from the README, so users understand where the data came from. Look up current docs online if you need to.
