+4. **Add debug logging** to track what's happening
+5. **Ensure student login works** to access handwriting features
+
+## Files to Check:
+
+- `public/index.html` - HTML structure
+- `public/styles.css` - Main styles (may need tablet overrides)
+- `public/tablet.css` - Tablet-specific styles
+- `public/handwriting.css` - Canvas styles
+- `public/js/handwriting.js` - Canvas functionality
+- `public/js/tablet-utils.js` - Tablet optimizations
+
+## Testing Steps:
+
+1. Open `tablet-test.html` to see working example
+2. Login as student (nate/nate123 or student1/123456)
+3. Start spelling game
+4. Check browser console for errors
+5. Try toggling between type/write modes
+6. Test canvas drawing if handwriting mode works
+
+## Browser Console Commands for Testing:
+
+```javascript
+// Check if handwriting is initialized
+console.log(window.handwritingRecognition);
+
+// Check canvas element
+console.log(document.getElementById('handwritingCanvas'));
+
+// Test toggle function
+window.toggleInputMode('handwriting');
+
+// Check CSS loading
+console.log(document.querySelector('link[href*="tablet.css"]'));
+```

-# process
-
-```require('process');``` just like any other module.
-
-Works in node.js and browsers via the browser.js shim provided with the module.
-
-## browser implementation
-
-The goal of this module is not to be a full-fledged alternative to the builtin process module. This module mostly exists to provide the nextTick functionality and little more. We keep this module lean because it will often be included by default by tools like browserify when it detects a module has used the `process` global.
-
-It also exposes a "browser" member (i.e. `process.browser`) which is `true` in this implementation but `undefined` in node. This can be used in isomorphic code that adjusts it's behavior depending on which environment it's running in. 
-
-If you are looking to provide other process methods, I suggest you monkey patch them onto the process global in your app. A list of user created patches is below.
-
-* [hrtime](https://github.com/kumavis/browser-process-hrtime)
-* [stdout](https://github.com/kumavis/browser-stdout)
-
-## package manager notes
-
-If you are writing a bundler to package modules for client side use, make sure you use the ```browser``` field hint in package.json.
-
-See https://gist.github.com/4339901 for details.
-
-The [browserify](https://github.com/substack/node-browserify) module will properly handle this field when bundling your files.

-Browser-friendly inheritance fully compatible with standard node.js
-[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
-
-This package exports standard `inherits` from node.js `util` module in
-node environment, but also provides alternative browser-friendly
-implementation through [browser
-field](https://gist.github.com/shtylman/4339901). Alternative
-implementation is a literal copy of standard one located in standalone
-module to avoid requiring of `util`. It also has a shim for old
-browsers with no `Object.create` support.
-
-While keeping you sure you are using standard `inherits`
-implementation in node.js environment, it allows bundlers such as
-[browserify](https://github.com/substack/node-browserify) to not
-include full `util` package to your client code if all you need is
-just `inherits` function. It worth, because browser shim for `util`
-package is large and `inherits` is often the single function you need
-from it.
-
-It's recommended to use this package instead of
-`require('util').inherits` for any code that has chances to be used
-not only in node.js but in browser too.
-
-## usage
-
-```js
-var inherits = require('inherits');
-// then use exactly as the standard one
-```
-
-## note on version ~1.0
-
-Version ~1.0 had completely different motivation and is not compatible
-neither with 2.0 nor with standard node.js `inherits`.
-
-If you are using version ~1.0 and planning to switch to ~2.0, be
-careful:
-
-* new version uses `super_` instead of `super` for referencing
-  superclass
-* new version overwrites current prototype while old one preserves any
-  existing fields on it
