Okay, let's start building a very basic foundation for an 8-bit style RTS game using HTML, CSS, and JavaScript. We'll begin with setting up the canvas and drawing a single static unit.

This sets up the basic HTML page with a canvas, styles it slightly, and includes a JavaScript file that draws a single yellow square representing a unit on the canvas. The imageSmoothingEnabled = false helps achieve a sharper, pixelated look.

Okay, let's improve the RTS foundation. We'll add:

1. Unit Selection: Click on a unit to select it.
2. Movement: Click on the map to move the selected unit to that location (basic, instant movement for now).
3. Multiple Units: Start with a couple of units.
4. Visual Grid: Draw a faint grid on the map.
5. Selection Indicator: Show which unit is selected.

Now you can:

• See a grid on the map.
• Click on one of the colored squares (units) to select it (a white border will appear).
• Click elsewhere on the map to instantly move the selected unit to that grid location.
• Clicking on empty ground deselects any unit.
