v3 mobile adaptation

v3.0 theme adaptation for mobile devices

With this major new update, many issues regarding the use of the theme on mobile devices have been fixed and general adjustments have been made in many places. Another major point is the revised color variable directory, right at the beginning of the .css file. Here you can now granularly customize the theme according to your wishes and preferences. Here in the Readme, you will also find a short description of the variables. Unfortunately, I have once again hit the 40,000-character limit, which is why the code has been highly compressed and is no longer as visually appealing. I apologize for this, but I couldn't think of another solution. Thanks again to @realrogue for sharing the tool CSSO (https://css.github.io/csso/csso.html) and to its creator. Additionally, the following bugs have been fixed:

Hover state is no longer applied on “Kagi Specials” and “Kagi Changelog” pages (html[data-apth=”/lens”])
Assistant: Code block color now adapts
Assistant: Tables now adapt their color
Assistant: Percentage display now matches the theme
Assistant: Model view update has been adjusted
Complete overhaul of the color variables → better customizability
Fixed a Kagi theme bug that affected the “Kagi Specials” and “Kagi Changelog” pages.
Hover boxes, "Advanced Search", dropdown menus for selection, and the timestamp on videos are now semi-transparent and glass-like
Discord user: "The assistant button looks funky for me on mobile, this is for Kagi.com itself without searching anything"
Messages (Kite) have been revised

@Zeuhx:

“The share icon have a different color for the desktop"
"Small color bug in Kagi Assistant"
"Theme seems not applied for News sections"
"A small theme color bug when I switch to a lens search"

@Temanor:

"Yeah, that one. The favicon just kinda gets pushed to the left."
"Mine is completely white." -> Ki Icon Bug in Assistant
"When opening this menu in the top right corner, the icon dissapears, and there is no X to close it either."
"This dropdown menu is slightly misalligned from the button."
"I didn't really have any issues with the current method of having the current model have white background [...]"
"Hover effect for the header on the changelog page"

Thank you for using the theme!
