Notes

You really fix some problems. It's not bad. But still problems with Seamless of menu. You should understand concept. Let me explain, for example, in the real world, look, we have a yoga mat, there are a lot of words written on the mat, the mat is rolled up, and therefore only part of the words are visible, we can unfold the mat then everything will be there words. All this time the yoga mat was one piece. In our implementation, for some reason I see visually two elements when the menu is open... And there should be one element. Also, when the menu is open, there is a word above the menu (with the currently selected category) and the same word is in the menu itself. That is, it turns out that there is one word above the menu, and this same word is in the menu itself - this is not right, this is bad! Based on this, I conclude for myself that some element on the site is a "rudiment"... The concept should be this: we have a whole menu, a single one! When we close the menu, this menu transforms into one linear menu (button), but it is still the same element. The same. All of this has a coherent, unbroken animation!!!! SEAMLESS ANIMATION! TRANSITION BETWEEN TWO STATES! WHEN YOU CHOOSE A CATEGORY THE MENU COLLAPS WITH THE RIGHT WORD. THE WORDS ALSO MOVES SMOOTHLY! Work through this very well, competently!! Allow yourself to THINK FOR A VERY LONG TIME!!!!! DON'T SIMPLIFY IMPROVEMENTS! DON'T SIMPLIFY ANYTHING!!!!



You will be working on WEB project. You are highly professional programmer! That ready and able to any task! You create perfect code. You are attentive and responsible to develop perfect Software. Wait for the lore of project.


Here is the lore (prequile, the code for this "lore" already exist.): "Create a mobile-focused single HTML file gallery using Waifu.pics API with these key requirements:

Primary Focus:
- Implement true MASONRY GRID layout - absolutely no gaps between images
- Make gallery fully adaptive and dynamic for all smartphone resolutions
- Include ALL image types and categories from API without exceptions
- Design must be minimalistic and modern, following Fluent Design principles
- Main focus on images - minimal UI elements

Technical Requirements:
- Single HTML file containing all necessary code (HTML, CSS, JavaScript)
- Pure client-side implementation, no server dependencies
- Efficient image loading system from API
- Smooth performance and transitions

Visual Implementation:
- Clean, modern interface emphasizing image content
- Proper spacing and proportions in masonry layout
- Subtle animations for interactive elements
- Light, unobtrusive design elements

Functionality:
- Complete integration with all Waifu.pics API endpoints
- Easy category navigation system
- Progressive content loading
- Responsive touch interactions

The solution should deliver a seamless, visually appealing mobile experience with perfect masonry grid implementation and full API integration.". DON'T WRITE NOW CODE! DON'T DO THIS IT YET!!!! NO CODE NOW!!! IT'S A LORE/HISTORY OF PROJECT! Wait in the next message from me a code that will implemented on this lore.


(Now you are start programming! We start! In the my code, endpoints a bit corrupted by asterisks (*), pls fix it.) Let's start:
