+
+## Development Phases
+1. **Phase 1**: Basic project structure and HTML layout
+2. **Phase 2**: Three.js renderer setup with camera and scene
+3. **Phase 3**: Track piece system with placement
+4. **Phase 4**: Grid and world management
+5. **Phase 5**: Junctions and signals logic
+6. **Phase 6**: Driver's eye view feature
+7. **Phase 7**: Game state save/load
+8. **Phase 8**: Testing and documentation
+
+## Next Steps
+- Create project file structure
+- Set up Three.js renderer
+- Implement basic track pieces
+- Build placement interface

+- WebGL 2.0 support
+- No server required - works as local file
+
+### Installation
+1. Clone or download this repository
+2. Open `index.html` in your browser
+3. Start building your railway empire!
+
+### Development Setup
+
+```bash
+# Navigate to project directory
+cd /a0/usr/projects/railtrack_pro
+
+# View development plan
+cat PLAN.md
+
+# Open in browser
+open index.html  # Mac

+# CSSOM
+
+CSSOM.js is a CSS parser written in pure JavaScript. It is also a partial implementation of [CSS Object Model](http://dev.w3.org/csswg/cssom/). 
+
+    CSSOM.parse("body {color: black}")
+    -> {
+      cssRules: [
+        {
+          selectorText: "body",
+          style: {
+            0: "color",
+            color: "black",
+            length: 1
+          }
+        }
+      ]
+    }
+
+
+## [Parser demo](https://acemir.github.io/CSSOM/docs/parse.html)
+
+Works well in Google Chrome 6+, Safari 5+, Firefox 3.6+, Opera 10.63+.
+Doesn't work in IE < 9 because of unsupported getters/setters.
+
+To use CSSOM.js in the browser you might want to build a one-file version that exposes a single `CSSOM` global variable:
+
+    ➤ git clone https://github.com/acemir/CSSOM.git
+    ➤ cd CSSOM
+    ➤ node build.js
+    build/CSSOM.js is done
+
+To use it with Node.js or any other CommonJS loader:
+
+    ➤ npm install @acemir/cssom
+
+## Don’t use it if...
+
+You parse CSS to mungle, minify or reformat code like this:
+
+```css
+div {
+  background: gray;
+  background: linear-gradient(to bottom, white 0%, black 100%);
+}
+```
+
+This pattern is often used to give browsers that don’t understand linear gradients a fallback solution (e.g. gray color in the example).
+In CSSOM, `background: gray` [gets overwritten](http://nv.github.io/CSSOM/docs/parse.html#css=div%20%7B%0A%20%20%20%20%20%20background%3A%20gray%3B%0A%20%20%20%20background%3A%20linear-gradient(to%20bottom%2C%20white%200%25%2C%20black%20100%25)%3B%0A%7D).
+It does **NOT** get preserved.
+
+If you do CSS mungling, minification, or image inlining, considere using one of the following:
+
+  * [postcss](https://github.com/postcss/postcss)
+  * [reworkcss/css](https://github.com/reworkcss/css)
+  * [csso](https://github.com/css/csso)
+  * [mensch](https://github.com/brettstimmerman/mensch)
+
+
+## [Tests](https://acemir.github.io/CSSOM/spec/)
+
+To run tests locally:
+
+    ➤ git submodule init
+    ➤ git submodule update

+ * The negative lookahead `(?![^(]*\))` ensures that the colon is not followed by a closing

+### resolve(color, opt)
+
+resolves CSS color

+  - `opt.currentColor` **[string][133]?**
+    - color to use for `currentcolor` keyword
+    - if omitted, it will be treated as a missing color,
+      i.e. `rgb(none none none / none)`
+  - `opt.customProperty` **[object][135]?**
+    - custom properties
+    - pair of `--` prefixed property name as a key and it's value,
+      e.g.
+      ```javascript
+      const opt = {
+        customProperty: {
+          '--some-color': '#008000',
+          '--some-length': '16px'
+        }
+      };
+      ```
+    - and/or `callback` function to get the value of the custom property,
+      e.g.
+      ```javascript
+      const node = document.getElementById('foo');
+      const opt = {
+        customProperty: {

+        }
+      };
+      ```
+  - `opt.dimension` **[object][135]?**
+    - dimension, e.g. for converting relative length to pixels
+    - pair of unit as a key and number in pixels as it's value,
+      e.g. suppose `1em === 12px`, `1rem === 16px` and `100vw === 1024px`, then
+      ```javascript
+      const opt = {
+        dimension: {

+      e.g.
+      ```javascript
+      const opt = {
+        dimension: {
+          callback: unit => {
+            switch (unit) {
+              case 'em':

+        }
+      };
+      ```
+  - `opt.format` **[string][133]?**
+    - output format, one of below
+      - `computedValue` (default), [computed value][139] of the color
+      - `specifiedValue`, [specified value][140] of the color
+      - `hex`, hex color notation, i.e. `#rrggbb`
+      - `hexAlpha`, hex color notation with alpha channel, i.e. `#rrggbbaa`
