         Welcome! I'm here to help you estimate tiles for your floor or wall.
 
-        👉 Start with **"Floor"** or **"Wall"**  
-        📐 Enter **length and width** (in feet)  
+        🔹 Start with **"Floor"** or **"Wall"**  
+        📀 Enter **length and width** (in feet)  
         📏 Then your tile size (in `mm` or `ft`) – like `600 x 600`, `2x2`, or `4`  
         📋 I’ll recommend tiles and calculate how many you need.
