Describe the bug
A clear and concise description of what the bug is.
Short Summary of the expected behavior:
When a web page is requested / served the Serial Monitor should not report errors.

Short Summary of the buggy behavior:
When the web page is served (index.html) in the Serial Monitor we get the following messages

[3709729][E][vfs_api.cpp:105] open(): /littlefs/style.css.gz does not exist, no permits for creation
[3709764][E][vfs_api.cpp:105] open(): /littlefs/favicon.png.gz does not exist, no permits for creation
[3711956][E][vfs_api.cpp:105] open(): /littlefs/favicon.png.gz does not exist, no permits for creation

To Reproduce
Steps to reproduce the behavior:

1. Into a Krake, load code from this PR: Enhancement/395 webpage bring up #477. Load both Firmware and LittileFS
2. Observe the Krake USB Serial Monitor
3. Boot the krake to a network. Observe the IP address on the LCD.
4. On a computer on the same network open that IP address in a browser.
5. The error message like above should be reported.

Notes in failed debug.
Testing of version Firmware V0.50. LittleFS "?0.1.0?

Why this happens
When a web browser requests a resource (like style.css), the server often checks for a Gzip-compressed version (e.g., style.css.gz) first to save bandwidth. If that file is missing, the underlying filesystem (LittleFS) throws this error because it cannot find the file and does not have permission to "create" it on the fly during a simple read request.

I asked:
Regarding, "Remove Conflicts: If you previously used SPIFFS on the same board, perform a full flash erase before uploading your LittleFS image to prevent partition table conflicts" How do I do this full flash erase? I am useing VSCode.

and got instructions:

Option 1: Using the PlatformIO GUI (Recommended)
This is the easiest way to erase the flash without typing commands.
Close the Serial Monitor: Ensure your Serial Monitor is closed, or the port will be busy.
Open PlatformIO: Click the Ant/Alien head icon on the left sidebar.
Navigate to Tasks: Open Project Tasks > [your_board_env] (e.g., env:esp32dev).
Erase Flash: Expand the Platform category and click Erase Flash.

I followed these instructions.
I loaded new firmware and LittleFS from the VSCode. After device boot I had to set the SSI and PW again.
The problem remains.

Bottom Line Failure

This debug was a failure.
