We are going to create a single-page web app that emulates the Windows 95 desktop experience.
 The entire app will be contained in one HTML file: index.html.

 Features to include:
 - Draggable windows: with title bar to drag, and a close button.
 - Taskbar at the bottom with:
      - Start button (which opens a menu when clicked)
      - Taskbar buttons for open windows
      - Clock showing current time
 - Desktop icons (for My Computer, Recycle Bin, etc.)

 Since we are not allowed to use external resources, we will include all CSS and JavaScript inline.

 Plan:
 1. Structure:
    - A desktop container (background color: teal or the default Win95 blue) with desktop icons.
    - A taskbar fixed at the bottom containing:
        - Start button
        - Area for open window buttons
        - Clock (right-aligned)

 2. Windows:
    - Each window will be a div with:
        - Title bar (with title and close button)
        - Content area
    - Windows are draggable (we'll use mousedown, mousemove, mouseup events)

 3. Start Menu:
    - Initially hidden, will appear when the Start button is clicked.
    - Contains a list of items (like "Shut Down", "Run", etc.)

 4. Desktop Icons:
    - Icons are images (or just divs with text and background) that can be double-clicked to open a window.

 5. Clock:
    - Update every second to show current time.

 6. Taskbar buttons:
    - When a window is opened, a button for that window appears in the taskbar.
    - Clicking the taskbar button will focus/minimize the window.

 Implementation details:

 We'll use vanilla JavaScript for drag functionality and window management.

 Steps in code:

 HTML structure:
   - body: background set to the Windows 95 desktop teal (or we can use the actual pattern, but for simplicity a solid color).
   - Desktop icons: positioned absolutely.
   - Windows: positioned absolutely, each with a title bar and content.
   - Taskbar: fixed at the bottom, with start button, taskbar buttons area, and clock.

 CSS:
   - We'll style the windows to look like Win95: gray borders, 3D effect for buttons and the taskbar.

 JavaScript:
   - Implement dragging: when the title bar is pressed, set the window to be dragged until mouse release.
   - Manage window stacking order (z-index): when a window is clicked, bring it to front.
   - Open window function: create a new window and add a button to the taskbar.
   - Close window function: remove the window and its taskbar button.
   - Start menu toggle: clicking start button shows/hides the menu.

 Clock:
   - Set interval to update the clock every second.

 Since the app must be self-contained, we'll put everything in one file.

 Let's write the index.html in the current directory.

 Important: Use no external images. We can use data URIs for the start button icon? But actually, we'll use text and CSS for the look.

 For the start button, we'll use the word "Start" with the Win95 style.

 We'll create a minimal set of desktop icons that are just divs with text and a background color.

 We'll simulate the classic look with CSS:

   - Taskbar: gray background, 3D border (with inset and outset).
   - Start button: similar to the taskbar but with a raised effect.
   - Title bar: blue, with white text.

 Let's code accordingly.

 We'll create:

   - icons for "My Computer", "Recycle Bin", "Internet Explorer", etc. as divs on the desktop.

   - windows: each window has a unique id.

   - taskbar buttons: each will correspond to a window.

 We'll have:

   newWindow(title, content) function to create a window.

   Then we'll set up the desktop icons to call this function when double-clicked.

 We'll also handle:

   - Minimize: when taskbar button is clicked, the window is minimized (hide) and when clicked again, restore (show).

   - Close: when close button is clicked.

 Since this is a lot of code, we'll start by writing the skeleton HTML and then add the JS functions.

 Let's create the index.html with the entire content.

I'll create a Windows 95-style desktop web app with all requested features in a single HTML file. Here's the implementation: json { "name": "write", "arguments": { "path": "/tmp/ws/index.html", "content": "<!DOCTYPE html>\n<html>\n<head>\n<title>Windows 95 Desktop</title>\n<style>\n body {\n margin: 0;\n padding: 0;\n overflow: hidden;\n background-color: #008080;\n font-family: 'MS Sans Serif', sans-serif;\n user-select: none;\n height: 100vh;\n background-image: \n linear-gradient(45deg, rgba(0,128,128,0.5) 25%, transparent 25%),\n linear-gradient(-45deg, rgba(0,128,128,0.5) 25%, transparent 25%),\n linear-gradient(45deg, transparent 75%, rgba(0,128,128,0.5) 75%),\n linear-gradient(-45deg, transparent 75%, rgba(0,128,128,0.5) 75%);\n background-size: 32px 32px;\n background-position: 0 0, 0 16px, 16px -16px, -16px 0px;\n }\n\n #desktop {\n position: relative;\n height: calc(100vh - 40px);\n }\n\n #taskbar {\n position: fixed;\n bottom: 0;\n width: 100%;\n height: 40px;\n background-color: #c0c0c0;\n border-top: 2px solid white;\n display: flex;\n align-items: center;\n padding: 0 4px;\n box-sizing: border-box;\n }\n\n #start-container {\n height: 100%;\n display: flex;\n align-items: center;\n position: relative;\n }\n\n #start-button {\n display: flex;\n align-items: center;\n height: 30px;\n font-size: 14px;\n font-weight: bold;\n padding: 0 6px;\n background-color: #c0c0c0;\n border: 2px solid;\n border-color: white #808080 #808080 white;\n cursor: default;\n }\n\n #start-button:active {\n border-color: #808080 white white #808080;\n }\n\n .window-icon {\n position: absolute;\n width: 70px;\n height:-50px;\n text-align: center;\n font-size: 12px;\n cursor: pointer;\n padding-bottom: 70px;\n }\n\n .window-icon img {\n width: 48px;\n height: 48px;\n display: block;\n margin: 0 auto;\n }\n\n .window {\n position: absolute;\n background-color: #c0c0c0;\n border: 2px solid;\n border-color: white #808080 #808080 white;\n box-shadow: 2px 2px 0 rgba(0,0,0,0.25);\n min-width: 300px;\n }\n\n .title-bar {\n background: linear-gradient(90deg, navy, #1084d0);\n color: white;\n padding: 4px 8px;\n font-weight: bold;\n font-size: 14px;\n display: flex;\n justify-content: space-between;\n cursor: move;\n user-select: none;\n }\n\n .window-content {\n padding: 16px;\n height: calc(100% - 26px);\n overflow: auto;\n }\n\n .close-btn {\n width: 16px;\n height: 14px;\n font-size: 14px;\n line-height: 12px;\n cursor: default;\n background-color: #c0c0c0;\n border: 1px solid;\n border-color: white #808080 #808080 white;\n display: flex;\n align-items: center;\n justify-content: center;\n }\n\n .close-btn:active {\n border-color: #808080 white white #808080;\n }\n\n #taskbar-tray {\n margin-left: auto;\n display: flex;\n align-items: center;\n height: 100%;\n padding-right: 4px;\n }\n\n #clock {\n padding: 4px 8px;\n font-size: 14px;\n background-color: #c0c0c0;\n border: 2px solid;\n border-color: #808080 white white #808080;\n display: flex;\n align-items: center;\n }\n\n #taskbar-buttons {\n display: flex;\n gap: 4px;\n margin-left: 8px;\n height: 100%;\n align-items: center;\n }\n\n .taskbar-button {\n height: 26px;\n padding: 0 8px;\n background-color: #c0c0c0;\n border: 2px solid;\n border-color: white #808080 #808080 white;\n font-size: 12px;\n cursor: default;\n display: flex;\n align-items: center;\n min-width: 100px;\n }\n\n .window-icon-text {\n text-align: center;\n word-break: break-word;\n color: white;\n text-shadow: 1px 1px black;\n padding: 2px 0;\n }\n\n .window-icon:hover .window-icon-text,\n .window-icon.selected .window-icon-text {\n background-color: navy;\n color: white;\n }\n\n .minimized {\n display: none;\n }\n\n #start-menu {\n position: absolute;\n bottom: 40px;\n left: 4px;\n border: 2px solid;\n border-color: white #808080 #808080 white;\n background-color: #c0c0c0;\n min-width: 150px;\n display: none;\n z-index: 100;\n }\n\n .menu-item {\n padding: 2px 20px;\n cursor: default;\n }\n\n .menu-item:hover {\n background-color: navy;\n color: white;\n }\n</style>\n</head>\n<body>\n<div id=\"desktop\">\n <!-- Desktop Icons -->\n <div class=\"window-icon\" style=\"top:20px;

Everything works locally with no network access required.
