    "# Intention\nMake a retro map of former Hollywood and Blockbuster Video Stores to celebrate National VHS Day.\n\nThe map itself is not as important as the nostalgia. These stores used to blanket our landscape. They were meeting spots. Most Americans spent many of their weekend nights perusing the shelves of these stores. The goal is to remind Americans of what once was. Nostalgia factor. They can remember what video stores were once in their local areas.\n\n# Aesthetic\n80s/90s pastiche. I want this to look 72DPI through and through. Everything about the map and the interface should be pixelated and blurred like a 72DPI VHS tape. Some horizontal staticy lines should flicker across the window like they would on a VHS. Intermittent choppiness is also good.\n\n# Map\n- Opens to entire US with 1980s thick state border lines and very simplified. Albers equal area with alaska and hawaii in lower left. (Probably use D3 for this. No video stores shown yet. This is almost like the main menu.\n- User can click on state, which does not highlight and is doesn't even look interactive. More like a \"hot key\" where the cursor just changes to a clicking hand.\n- When the user clicks the state, load the simplified state outline with 72DPI dots geolocated on top of it. The user may zoom in to see the stores in detail. Dot clusters shouldn't be used, as the user will want to see where their old store was. But no streets or any details should be provided. They can zoom in up to 8 times the current zoom level, and they can pan the state, but they cannot pan the state off the viewport nor may they zoom out past the state. When zoomed out as far as possible over any state, the state should always fill either the height or width of map canvas.\n- When a user clicks on a store, provide the store chain name, address, open date and close date (when available).\n- Have a huge BACK ARROW button prominently displayed whenever the user is zoomed in on a state. The back arrow takes the user back to the entire US.\n- Also, come up with a nostalgic, witty title and subtitle involving VHS and the socialness of meeting at a location to pick movies.\n- Make sure the map works in landscape mode on mobile devices.\n\n# Aesthetic\n- 1980s TV newscast style GUI elements (big, brash, large text)\n- random and variable VHS style flickering and warpiness\n- 1980s TV local newscast colors and graphics style\n- Cartography should be grossly simplified. Graphics very large due to bad DPI/resolution. Make this look like 1980s/1990s television recorded on VHS and being played back on a modern a device.\n\nAgain, map itself should be very simple state outlines, and point symbols. Hollywood Video stores can be purple. Blockbuster stores blue or yellow.\n\nInclude a gaudy note that says \"Click a state to find your next rental!\"\n\n# Sources modal\nShould be very hidden. Don't want to take away from the aesthetic. lower left perhaps. Perhaps a \"Call Now\" button or similar. When it opens, very blocky and chunky 1980s style text.\n\n- Cartographer: Ian Muehlenhaus (link to www.muehlenhaus.com)\n- Made with Web Mapper GPT (link to www.webmapgpt.com)\n- Dataset from GIS Dataset GPT (link to that public GPT)\n- Dataset Geopackage (link to the geopackage)\n- APIs Used: list APIs\n- Dedicated to Steve, former owner of \"8th Street Video on 9th Street\" in Duluth, Minnesota. \"They're all good movies!\" You are missed.\n\nThanks!",
    "Are you almost done with the package building? I'm sorry, but I'm just a little confused, as I am able to communicate with you but you didn't return an answer.\n\nRemember, you don't ever produce images. You produce web maps. I think maybe that was forgotten when you started thinking about the previous task... but I am just guessing. Thanks again!",
    "Requested final tweaks: update dataset source to GIS Dataset Doctor GPT, add provenance link to sources modal, remove unnecessary modal/legend/popup text, replace popup opened/closed with tape-label closure text, change LOCAL 72DPI to a Betamax nod, and rename LEGEND to VHS Rental Stores."
