+                **How to format your data:**
+                - Your file must be a table (CSV, XLS, XLSX, or Parquet).
+                - **One row per timeseries.** Each row is treated as a separate series.
+                - If you want to **name** each series, put the name as the first value in **every** row:
+                  - Example (CSV):  
+                    `AAPL, 120.5, 121.0, 119.8, ...`  
+                    `AMZN, 3300.0, 3310.5, 3295.2, ...`  
+                  - In that case, the first column is not numeric, so it will be used as the series name.
+                - If you do **not** want named series, simply leave out the first column entirely and have all values numeric:
+                  - Example:  
+                    `120.5, 121.0, 119.8, ...`  
+                    `3300.0, 3310.5, 3295.2, ...`  
+                  - Then every row will be auto-named “Series 0, Series 1, …” in order.
+                - **Consistency rule:** Either all rows have a non-numeric first entry for the name, or none do. Do not mix.
+                - The rest of the columns (after the optional name) must be numeric data points for that series.
+                - You can filter by typing in the search box. Then check or uncheck individual names before plotting.
+                - Use “Check All” / “Uncheck All” to quickly select or deselect every series.
+                - Finally, click **Plot Forecasts** to view the quantile forecast for each selected series (for 64 steps ahead).

-                **How to format your data:**
-                - Your file must be a table (CSV, XLS, XLSX, or Parquet).
-                - **One row per timeseries.** Each row is treated as a separate series.
-                - If you want to **name** each series, put the name as the first value in **every** row:
-                  - Example (CSV):  
-                    `AAPL, 120.5, 121.0, 119.8, ...`  
-                    `AMZN, 3300.0, 3310.5, 3295.2, ...`  
-                  - In that case, the first column is not numeric, so it will be used as the series name.
-                - If you do **not** want named series, simply leave out the first column entirely and have all values numeric:
-                  - Example:  
-                    `120.5, 121.0, 119.8, ...`  
-                    `3300.0, 3310.5, 3295.2, ...`  
-                  - Then every row will be auto-named “Series 0, Series 1, …” in order.
-                - **Consistency rule:** Either all rows have a non-numeric first entry for the name, or none do. Do not mix.
-                - The rest of the columns (after the optional name) must be numeric data points for that series.
-                - You can filter by typing in the search box. Then check or uncheck individual names before plotting.
-                - Use “Check All” / “Uncheck All” to quickly select or deselect every series.
-                - Finally, click **Plot Forecasts** to view the quantile forecast for each selected series (for 64 steps ahead).
