app

- Can include business logic and state management - Can include data fetching and caching logic - Should use original spelling for HTML-native events and `camelCase` for custom events - Props and markup attributes should be listed alphabetically - Use JS Objects and Arrays for CSS classes and styles when they are dynamic - Whenever there can be repetition in the component's markup, if it's too small to be decoupled as a separate component — use Svelte 5's `{#snippet}` + `{@render}`
