Product page builded with Svelte and WindiCss

hi, your solution looks pretty good!... I used svelte in mine as well.

Overall looks good in my opinion, I'll just leave a couple of suggestions.

I think the lib folder could be a little bit misleading (they're mostly used for organizing modules), instead, I think you can omit it, and leave your components like this

src/components
src/components/cart
src/components/icons
src/stores

Another good recommendation to follow I think it's to avoid modifying stores directly, instead, have "action" functions that you can reuse in your components, something like this

const isVisible = writable(false)

function show() {
  isVisible.set(true)
}

function hide() {
  isVisible.set(false)
}

export default { isVisible, show, hide }

Hope this is useful
