vibe coding, coding with a good vibe, where you’re not stressing about bugs or edge cases too much but rather enjoying the problem-solving process
trying use mcp tool and playwright to guide llm to write a page and refine the style of page until the page machs the design picture
- It’s a long and pretty complex workflow. it works best for pages with a simple style or ones that closely follow UI frameworks.
- work terribly for custom pages. modules like claude-3.7, chatgpt-5 are must blind rebatos, they are really struggle to identify details like color/border/shadow, and sometimes can’t even detect them at all

- the user’s image could be a screenshot or downloaded from the design platform, so the dimensions might not match the design size exactly.

# threshold converts the image into a black-and-white image, acts as a cutoff point, deciding which pixels become part of the white edges and which pixels are ignored (turned black).
magick out.png -edge 1 -threshold 6% edges.png

morphology applies various morphological transformations to an img,

# Dilate expands the white shapes, making a shape bigger
magick edges.png -morphology Dilate Disk:3 output.png
# Thinning removes pixels in a way that reduces the size of features in the image while preserving the general shape
morphology + Thinning = reduce unnecessary pixels

kelly criterion
- b: represents the ratio of profit to your stake if you win.
  - If b is large (you win a lot when you win), Kelly will tell you to bet more.
  - If b is small (low reward), Kelly will tell you to bet less.
- p: probability of winning
- q: probability of losing, 1 - p
  
  kelly criterion = (bp - q) / b * captial
  for example:
  - p: 0.6, q: 0.4, b: 1, kelly criterion is 0.2
  - captial: $100, bet $20 at each time.
    - if win, captial becomes $120 and the invest capital is $24 at the next time.
    - if lose, captial becomes $80 and the invest capital is $16 at the next time.
css relative color
- it makes easy to generate relative colors, like darker / lighter
  
  Hue (°) Color
  
  0° Red
  
  60° Yellow
  
  120° Green
  
  240° Blue
  
  300° Purple
- color-mix(in srgb, color1, color2 percentage), color module, color1, color2 the percentage of mix level
- hsl, hue/staturation/lightness, hsl(from red calc(h + 90) c h)
- lch, lightness / chroma / hue, lch(from red calc(h + 90) c h)
  -hsl is calculated from pure RGB. whereas hcl fixs uniformity issues of hue / chroma / lightness. if a single color component is changed, hcl will produces a smoother visual transition
  - staturation vs chroms, staturation is compared with pure gray. while chrome is compared to a neutral gray of the same lightness
- OKLCH, the human vision 2.0 of hcl
- xyz, red/green, brightness, blue/green

Hue (°)	Color
0°	Red
60°	Yellow
120°	Green
